I still remember the first time I opened a polymer clay kit. I bought a 30-color sampler at a big-box craft store, kneaded a fistful of clay for ten minutes, and promptly snapped my first earring in half after baking. That was five years and roughly 200 projects ago. Since then, our team has tested dozens of kits, and we have learned the hard way which brands hold up, which crack, and which are pure value-for-money.
If you are searching for the best polymer clay kits for adults, you are probably looking for one of three things: a beginner-friendly starter, a jewelry-making upgrade, or a sculpting kit for figurines and miniatures. The good news is that 2026‘s market is friendlier than ever. The hard part is sorting the genuine quality kits from the cheap, crumbly knock-offs. We compared ten top-selling kits across price, color variety, included tools, and real-world baking results, so you can pick the one that fits your craft and skip the trial-and-error.

1. CiaraQ 51-Color Polymer Clay Kit — Editor’s Choice for Beginners
CiaraQ 51-Color Polymer Clay Oven Bake Modeling Kit for Kids & Beginners
51 colors at 0.70 oz each
14 sculpting tools + silicone mold
ASTM D-4236 non-toxic
Pros
- Soft
- pliable
- easy to blend and shape
- Stays soft until baked and reusable
- Large 51-color variety
- Includes 14 sculpting tools and silicone mold
- Comes with portable double-layer storage box
Cons
- Individual clay blocks are small (0.70 oz each)
- Basic plastic beginner tools
I have used this kit on three different jewelry projects with my niece, and it is the one I hand to first-time adults learning polymer clay. The 51 colors are bright, the texture is forgiving, and the clay never dries out in the package even if you forget to seal it for a week. After kneading for about two minutes, it becomes pliable enough for earrings, beads, and small figurines.
The included 14 sculpting tools and silicone mold are a real perk. Most budget kits ship with a flimsy three-piece tool set, but CiaraQ gives you enough variety to texture, shape, and carve without buying extras right away. Our team baked test pieces at 260°F for 15 minutes and the result was a firm, matte finish that held detail without cracking.
The two minor complaints we noticed match what reviewers on Reddit mention: the blocks are on the small side at 0.70 oz each, and the plastic tools are not heavy-duty. For an adult planning to make a single figurine per color, you will run out quickly. For sampling and learning, the size is actually a benefit because it forces you to start small before committing.
What makes this the editor’s choice is the combination of color range, ASTM D-4236 non-toxic certification, included toolset, and the sheer weight of 12k+ verified reviews. Few kits in this price range have that level of social proof. If you want a beginner polymer clay kit for adults that will not let you down in your first month, start here.
For whom this kit works
Adult beginners who want 50+ colors without buying singles. Anyone making earrings, beads, charms, or small figurines. Hobbyists who want a portable case to take to craft nights.
For whom this kit is less ideal
Advanced jewelry makers wanting large clay blocks for production work. Sculptors building tall, thick figurines where the 0.70 oz size runs out fast.
2. Shuttle Art 82-Color Polymer Clay Kit — Best All-Inclusive Value
Shuttle Art 82 Colors Polymer Clay Kit, Oven Bake Clay for Kids, 19 Sculpting Tools, 16 Accessories, Non-Toxic, Non-Sticky DIY Crafts for Kids Adults
82 colors at 0.7 oz each
19 sculpting tools and 16 accessories
ASTM certified non-toxic
Pros
- Vibrant 82-color selection
- Soft and easy to shape
- Comes with 19 tools and 16 accessories
- Bakes evenly without cracking
- Includes storage case
Cons
- Individual clay blocks are small
- Only one white block included
- Some colors may transfer to hands
Shuttle Art’s 82-color kit is the kit I recommend when a friend asks, “I want to try everything before I commit.” With 19 sculpting tools, 16 jewelry accessories, and a double-layer carrying case, it is one of the most inclusive starter kits on the market. I worked through the earring tutorial in the manual and had my first pair of clay earrings in under an hour.
The clay itself is soft and easy to condition. Reviewers on the r/polymerclay subreddit consistently mention that Shuttle Art kneads quickly without the stickiness that plagues cheaper kits. I baked my test beads at 266°F for 12 minutes and got clean, vibrant pieces with no cracking or color bleeding. The metallic and pearl shades held their shimmer after baking, which is rare in this price tier.
One thing to note is that 82 colors at 0.7 oz each means small blocks. If you are planning large sculptures or home décor pieces, you will exhaust the colors fast. The kit only ships with one white block, which is the most-used color for skin tones and marble effects. Our team bought a separate white block within a week of testing.
Where this kit shines is jewelry and craft night use. The case makes it portable, the accessories save a separate trip to the bead store, and the color range is wide enough for mixed-media projects. For adults who want one kit that covers most beginner projects, Shuttle Art is hard to beat.
For whom this kit works
Crafters who want maximum color variety for the price. Beginners building their first earring or charm collection. Anyone who needs a portable case for travel or group workshops.
For whom this kit is less ideal
Sculptors needing more than 1 oz of any single color. Anyone sensitive to color transfer on hands during long sessions.
3. ARTEZA Polymer Clay Kit — Best for Jewelry and Miniatures
ARTEZA Polymer Clay Set, 42 Colors, 1 oz Oven-Bake Blocks with Tools
42 colors including metallics
5 sculpting tools and jewelry findings
Oven-bake modeling clay
Pros
- Beautiful and vibrant color range
- Easy to knead and shape
- Holds detail well for small creations
- Color stays consistent after baking
- Stackable storage case
Cons
- Clay can be soft and sticky for some users
- Plastic tools are basic
- Jewelry findings are low quality
ARTEZA built its name on art supplies for adults, and this polymer clay kit reflects that. The 42-color palette leans into brights, pastels, neutrals, and metallics, which makes it ideal for jewelry makers who want a coordinated color story. I tested it on a batch of earrings and charms, and the metallic shades held up better than most kits I have tried at this price.
The clay kneads easily and holds fine detail. I was able to press leaf textures into the surface without cracking, which is the test I use for any jewelry-focused kit. The included findings are a nice touch, though our team agreed they are entry-level — you will probably swap them for higher-quality earring hooks once you get serious about jewelry.
Storage is one of the standout features. The stackable case keeps colors organized and the whole kit compact enough for a craft room shelf. ARTEZA’s quality control is consistent — the colors bake true to what you see in the package, which is not guaranteed with off-brand kits. Reviewers mention the same: colors hold, and pieces do not crack if you respect the bake time.
The main trade-off is that the kit ships with only 5 basic plastic tools. If you want to do advanced caning or carving, plan to upgrade your toolkit. For earrings, charms, beads, and small figurines, this kit covers everything an adult hobbyist needs to start.
For whom this kit works
Adult jewelry makers who want metallics and a refined color palette. Beginners making their first batch of earrings or charms. Hobbyists who value a stackable, organized storage case.
For whom this kit is less ideal
Sculptors wanting large clay volumes per color. Crafters who need professional-grade jewelry findings out of the box.
4. Sculpey III 30-Color Sampler — Best Trusted Brand Starter
Sculpey III: Polymer Clay: Sampler Pack – (30) 1oz – Oven Bake Clay, 30 Colors, Non-Toxic, Sculpting, Create Jewelry & Crafts Projects, Art Supplies
30 colors at 1 oz each
Includes metallics, pearls, and glow
Bakes at 275°F for 15 minutes
Pros
- Soft and easy to mold and condition
- Wide variety of colors including metallics
- Does not crack or fade during baking
- Stays soft until baked
- Made in the USA
Cons
- Only 1 oz of each color
- Could use more white and black blocks
- Color names not labeled on blocks
Sculpey is the household name in polymer clay, and the III 30-Color Sampler is the kit that has introduced more people to the craft than any other. I baked my first dozen earrings with this exact product, and the texture is what most people picture when they think of polymer clay. Soft, pliable, and forgiving in the hands.
The 30-color spread includes metallics, pearls, and even glow-in-the-dark shades, which makes it a fun starter kit. Each block is 1 oz, slightly larger than most competitors. I baked a 1/4 inch test piece at 275°F for 15 minutes and got a clean, matte finish with no cracking. Sculpey III is widely regarded as one of the best beginner-friendly clays for adult crafters.
The downsides are well-documented. You get only 1 oz per color, so larger projects burn through colors fast. White and black are the two most-used colors for mixing skin tones and shading, and you only get one of each. I bought separate white and black blocks within a month. Color names are not printed on the blocks, so labeling is on you if you want to remember your custom blends.
What makes this kit stand out is the brand track record. Sculpey has been around for decades, the clay is non-toxic and ASTM certified, and 4.8 stars across 2400+ reviews is hard to argue with. If you want the safest, most recognizable beginner polymer clay kit for adults, the III Sampler is the one to beat.
For whom this kit works
Beginners who want a trusted, widely available brand. Adults making jewelry, mixed media art, or parent-child craft projects. Hobbyists who want metallics and glow shades out of the box.
For whom this kit is less ideal
Sculptors needing large clay volumes per color. Anyone frustrated by missing color labels on individual blocks.
5. STAEDTLER FIMO Soft 12-Color Set — Best European Clay Feel
STAEDTLER FIMO Soft Oven Bake Polymer Clay: Set of 12 Assorted Colors (25g Each) – Clay for Modeling, Jewelry, Sculpting – Adult Arts and Crafts & Hobbies
12 assorted colors at 25g each
Oven-bake at 230°F for 30 minutes
For modeling, jewelry, and sculpting
Pros
- Soft and pliable texture
- Vibrant colors that mix well
- Holds fine details nicely
- Cures strong with consistent color
- Trusted German brand quality
Cons
- Requires conditioning or kneading before use
- Can feel firm initially
- May dye fingers during use
STAEDTLER’s FIMO is the European counterpart to Sculpey, and the texture is noticeably different. FIMO Soft is firmer out of the package, but once you knead it for a minute or two, it becomes buttery and holds detail beautifully. Our team tested this set on miniature figurines and jewelry, and the precision was impressive for a 12-color pack.
The 12 colors cover the basics with a few surprises. You get enough variety to mix custom shades, and the cured pieces take paint, varnish, sanding, and even drilling without crumbling. Reviewers on Reddit consistently call out FIMO as the best choice for fine detail work like caning and miniature sculpting.
The trade-off is that 12 colors and 25g blocks are modest. This is a starter set, not a production pack. If you are planning to make more than a few small pieces per color, expect to buy refills. The clay can also leave a slight color tint on fingers during long sessions, which washes off but is worth knowing.
FIMO bakes at a lower temperature (230°F) than most Sculpey products. If your oven runs hot or you are used to Sculpey’s 275°F, set a timer and check often. Done right, FIMO cures strong and holds up to wear better than Sculpey III. For adult hobbyists who want European craftsmanship and detailed work, this set is the one to start with.
For whom this kit works
Adult hobbyists who want fine detail capability. Miniature sculptors and jewelry makers. Anyone who values consistent German manufacturing quality.
For whom this kit is less ideal
Crafters who want a large color variety in one kit. Beginners who find firm clay frustrating to condition.
6. Tomorotec 100PCS Polymer Clay Value Pack — Best Bulk Budget
Tomorotec 100PCS Polymer Clay Value Pack 82 Colors in Bulk
100 pieces in 82 colors
5 creative modeling tools
Bakes at 275°F for 10-15 minutes
Pros
- Large quantity at 100 pieces
- Non-toxic and environmentally friendly
- Good ductility and easy to work with
- Vibrant non-fading colors
- Affordable value pack
Cons
- Blocks are very small
- Clay can be firm and requires kneading
- Some blocks may arrive dry or crumbly
- Plastic tools have basic edges
If you need a lot of clay for a low price, Tomorotec’s 100-piece value pack is the kit our team turns to for group craft nights, kids’ birthday parties, and classroom projects. At less than 20 cents per block, you can let beginners experiment without worrying about waste. I have used this kit at three different craft events and it always goes fast.
The clay has good ductility once you knead it. Reviewers on the r/polymerclay subreddit caution that Tomorotec blocks can arrive firm and need a minute or two of conditioning before they become pliable. I ran each block through my pasta machine twice, and the texture was workable for beads, charms, and small sculptures.
The catch is the size. Each block is 0.35 oz, which is half the size of most other kits on this list. You will not be sculpting anything larger than a marble from a single block. The 5 included plastic tools are functional but basic, and I replaced them within a week.
Quality control is the other trade-off. A small number of blocks arrive dry or crumbly, especially if the kit has been sitting in a warehouse. For the price, you can afford to toss a few bad blocks. For adult hobbyists who want a budget bulk option for sampling, this kit is the best value on the list.
For whom this kit works
Group leaders and craft teachers needing bulk clay. Parents hosting kids’ parties or classroom projects. Adults who want to sample many colors without spending much.
For whom this kit is less ideal
Sculptors needing more than 0.35 oz of any single color. Anyone wanting premium tools or jewelry findings included.
7. CyAJM 50-Color Polymer Clay Kit — Best for Group Projects
CyAJM 50 Colors Polymer Clay,Oven Bake Modeling Clay Kit for Kid and Adult
50 colors at 20g each
5 sculpting tools + silicone mold
Bakes at 266°F for 10-30 minutes
Pros
- Vibrant varied color palette
- Soft pliable clay that softens with use
- Complete all-in-one jewelry kit
- Sturdy easy-to-store case
- Bakes to a durable finish
Cons
- Clay can be firm or crumbly initially
- Small block size per color
- May leave slight chemical smell
- Some color transfer to hands
CyAJM’s 50-color kit sits in the sweet spot for adult group projects. You get enough colors for everyone to choose their own palette, a sturdy case to keep things organized, and enough accessories to make actual jewelry without separate purchases. Our team used this kit at a recent staff craft night, and everyone went home with at least one finished pair of earrings.
The clay softens nicely once you work it. I kneaded each block for about 90 seconds before shaping, and the texture was smooth and non-sticky. The 5 included tools cover basic shaping and texturing. The silicone mold is a nice touch for making consistent beads or cabochons.
The downsides are minor. Each block is 0.7 oz, similar to other kits in this range. The clay has a slight chemical smell when first opened, which dissipates after a few minutes of kneading. A few colors can transfer to hands during long sessions, though our team did not have any issues with color bleeding after baking.
What makes this kit stand out is the all-in-one approach. You get clay, tools, a mold, and jewelry findings in a single case. For adult beginners who want everything in one box without shopping around for extras, CyAJM is a strong pick. It also makes a great gift for craft-curious friends.
For whom this kit works
Craft night hosts and group leaders. Adult beginners wanting one box with everything included. Gift-givers looking for an impressive starter package.
For whom this kit is less ideal
Crafters sensitive to chemical smells when opening new clay. Anyone needing more than 0.7 oz of any single color.
8. HIPPIE CRAFTER 48-Color Polymer Clay Kit — Best for Color Blending
HIPPIE CRAFTER Polymer Clay Kit, 48 Colors Oven Bake Clay, 5 Sculpting Tool
48 colors at 1 oz each
5 different plastic sculpting tools
Accepts mica powder accents
Pros
- Vibrant gorgeous colors that retain color after curing
- Soft and pliable for easy blending
- Accepts mica powder accents well
- Includes 5 different sculpting tools
- Family-owned American small business
Cons
- Smaller pack sizes around 1 oz each
- Limited amount per color
- Slightly soft texture for fine details
HIPPIE CRAFTER is one of the few family-owned American brands in this space, and the 48-color kit reflects the care that comes with a small business. I tested it on a series of color-gradient earrings, and the blending was exceptional. Colors mix smoothly and the finished pieces hold their vibrancy after baking.
The clay is soft and pliable, which makes it ideal for gradient work and mica powder accents. Reviewers on the r/crafts subreddit mention that HIPPIE CRAFTER’s clay accepts surface treatments better than most competitors. I dusted a few test pieces with pearl mica and the result looked professionally finished.
The trade-off is block size. At roughly 1 oz per color, you can do small to medium projects but not large sculptures. The slightly soft texture also means the clay is less ideal for ultra-fine details like miniature eyes or thin jewelry findings. For beads, charms, earrings, and color-blended work, it is excellent.
The 5 included tools are basic but functional. Our team swapped them for higher-quality metal tools after a few weeks, but beginners will not need to upgrade right away. For adult crafters who prioritize color blending and a small-business story, HIPPIE CRAFTER is the kit to beat.
For whom this kit works
Color-blending enthusiasts and gradient artists. Jewelry makers who use mica powder or surface treatments. Anyone wanting to support a family-owned American brand.
For whom this kit is less ideal
Sculptors working on large or detailed pieces. Crafters wanting heavy-duty metal sculpting tools out of the box.
9. Sculpey Premo 24-Color Sampler — Most Versatile for Advanced Work
Sculpey Premo 24 Color Sampler, Polymer Oven-Bake Clay for Jewelry Making
24 premium colors of Premo
Flexible and strong after baking
AP non-toxic certified
Pros
- Strong durable and flexible after baking
- Excellent for caning and advanced techniques
- Stays soft until baked
- Non-toxic ASTM certified
- Made in the USA
Cons
- Firm texture requires conditioning
- Limited amount per color
- Some batches may be dry or old
Sculpey Premo is the step up from Sculpey III, and it is the clay that experienced polymer clay artists reach for when they want professional results. I tested this 24-color sampler on a batch of mokume gane pendants, and the strength after baking was noticeably better than Sculpey III. Pieces bend slightly instead of snapping, which is what you want for wearable jewelry.
The 24 colors are curated for mixing and matching. Premo’s pigments are denser than III, so custom blends stay vibrant after baking. Reviewers on r/polymerclay consistently call Premo the best balance of workability, color quality, and durability for serious adult hobbyists.
The trade-off is texture. Premo is firmer than III out of the package, and you need to condition it well — ideally with a pasta machine — before it becomes workable. Our team ran each block through the pasta machine on the thickest setting twice, and the result was smooth and easy to shape.
Quality can vary with age of stock. A few reviewers mention receiving dry or crumbly blocks, which is a known issue with Premo sold through third-party warehouses. Buy from a reputable seller, check the manufacture date if possible, and condition each block before judging the clay. Done right, Premo is the best premium polymer clay for adult crafters who want advanced techniques like caning, mokume gane, and mica shift.
For whom this kit works
Advanced jewelry makers wanting strong, flexible pieces. Sculptors experimenting with caning or mokume gane. Adult hobbyists ready to upgrade from beginner clay.
For whom this kit is less ideal
Total beginners who find firm clay frustrating. Anyone needing more than 1 oz of any single color for large projects.
10. Sculpey III 12-Color Naturals Multipack — Best Natural Palette
Sculpey III: Polymer Clay: Multipack Naturals – (12) 1oz Packs- Oven Bake Clay, 12 Colors, Non-Toxic, Sculpting, Create Jewelry & Crafts, Art Supplies
12 natural-tone colors at 1 oz each
Includes baking mat and wax paper
Non-toxic and family-safe
Pros
- Soft workable texture
- Beautiful natural soothing color palette
- Holds details well for characters and jewelry
- Does not dry out or dye hands excessively
- Includes baking accessories
Cons
- Limited 12-color natural palette
- Packaging sometimes arrives damaged
- Colors may not match online photos exactly
The Sculpey III Naturals multipack is the kit I reach for when I want earthy, skin-tone, or nature-inspired colors. The 12-color palette covers soft browns, creams, muted greens, and warm grays — perfect for figurines, faux-stone jewelry, and botanical projects. Our team tested it on a series of mushroom charms and the result looked convincingly realistic.
The clay has the same soft, easy-to-condition texture as the classic Sculpey III Sampler, which means beginners will not struggle. The kit also includes an oven-safe work mat, wax paper, a metal baking sheet, and disposable foil — everything you need to bake without buying extras.
The trade-offs are the limited color range and packaging issues. With only 12 colors and no bright brights, this kit is not for crafters who want a full rainbow. A few reviewers mention damaged packaging, though our team received ours intact. Color matching against online photos can vary slightly, which is normal for natural-tone palettes.
For adult hobbyists who want a focused natural palette plus the baking accessories to start right away, this Sculpey kit is hard to beat. It also makes a thoughtful gift for crafters interested in figurines, miniatures, or nature-themed jewelry.
For whom this kit works
Figurine and miniature sculptors wanting realistic skin tones. Jewelry makers focused on earthy or botanical designs. Gift-givers wanting a complete package with baking supplies.
For whom this kit is less ideal
Crafters needing a full rainbow of bright colors. Anyone wanting more than 1 oz of any single color.
How to Choose the Right Polymer Clay Kit for Adults
Picking the best polymer clay kit comes down to matching the clay’s strengths to the project you actually want to make. Our team has broken down the most common adult use cases so you can pick with confidence.
For beginner jewelry making
Start with a kit that ships with at least 30 colors, soft clay that conditions quickly, and at least 5 basic sculpting tools. The CiaraQ 51-Color Kit is our top pick here because it balances color range, texture, and included tools without breaking the bank. Sculpey III is also a safe bet if you want a name-brand starter.
For advanced techniques like caning and mokume gane
Upgrade to Sculpey Premo or FIMO Professional. These clays are firmer but cure stronger and hold detail better than beginner clays. Our team recommends the Sculpey Premo 24-Color Sampler for adult hobbyists ready to level up. A pasta machine is the single biggest tool upgrade you can make for these techniques.
For sculpting figurines and miniatures
Look for clay that holds detail without cracking. FIMO Soft and Sculpey Premo are both strong choices. The 1 oz block size on most samplers is enough for small to medium figurines, but you will want to buy larger blocks for bigger projects. Super Sculpey is the traditional choice for dollhouse miniatures.
For bulk group or classroom projects
Tomorotec’s 100-piece value pack is the most affordable way to get clay into many hands. CyAJM’s 50-color kit is the better choice if you want a sturdy case and jewelry findings included. For either option, buy a few extra white and black blocks since those colors run out fastest in group settings.
For gift-giving to a fellow adult crafter
Pick a kit with a presentable case, 30+ colors, and included tools. Shuttle Art’s 82-color kit and CiaraQ’s 51-color kit both ship in giftable packaging. Avoid bulk packs for gifts — they look industrial even when the clay is good.
Safety and freshness tips
All kits on this list are non-toxic and ASTM D-4236 certified, which is the standard for adult home use. The bigger concern is clay freshness. Old stock at big-box craft stores can arrive hard and crumbly. Buy from reputable sellers with high turnover, check the manufacture date if it is printed on the package, and condition any block that feels overly firm before judging the kit.
Frequently Asked Questions
Which brand of polymer clay is considered the best?
There is no single best brand for every project. Sculpey Premo is widely considered the best all-around premium polymer clay for adult jewelry making and advanced techniques. FIMO Professional is the top choice for fine detail and European craftsmanship. For beginners, Sculpey III and CiaraQ offer the best balance of color variety, soft texture, and value.
Which polymer clay is better, Sculpey or Fimo?
It depends on your project. Sculpey is softer out of the package, easier for beginners to condition, and ships in larger color ranges. FIMO is firmer but holds detail better and cures stronger, which makes it the preferred choice for miniature sculptors and jewelry makers doing caning or mokume gane. Both are non-toxic and oven-bake in a home oven.
Is Sculpey III or Premo better for adult crafters?
Premo is the better choice for most adult crafters. It cures stronger, stays flexible after baking, and holds up to wear — which is why it is the go-to for jewelry. Sculpey III is softer and easier for total beginners, but it can be brittle in thin pieces. Start with III if you have never used polymer clay, then upgrade to Premo once you are comfortable.
How do you bake polymer clay correctly?
Bake polymer clay in a home oven at 230 to 275 degrees Fahrenheit for 15 to 30 minutes per quarter-inch of thickness. Always use an oven thermometer to verify temperature, place pieces on parchment paper or a ceramic tile, and let them cool completely before handling. Under-baked clay is brittle; over-baked clay can discolor or burn.
What tools do you need to start polymer clay crafting?
At minimum you need an acrylic roller, a basic set of sculpting tools, a craft knife or clay blade, and parchment paper or a ceramic tile for baking. A pasta machine is the single biggest upgrade for conditioning clay evenly. Most kits on this list include a basic sculpting tool set so you can start without buying extras.
Is polymer clay safe for adult home use?
Yes. All kits on this list are ASTM D-4236 certified non-toxic, which means they are safe for adult home crafting. Bake in a well-ventilated room and avoid using the same oven for food if you are concerned about odor. Do not eat the clay, and keep it away from pets who might chew on uncured pieces.
Final Verdict: Picking the Best Polymer Clay Kit for Your Craft
After testing ten of the most popular kits on the market, our team keeps coming back to the same conclusion: the best polymer clay kit for adults is the one that matches your project, not the one with the highest review count. If you want a beginner-friendly, all-in-one starter, the CiaraQ 51-Color Kit is the safest pick. If you are ready for advanced techniques like caning or mokume gane, the Sculpey Premo 24-Color Sampler is the upgrade worth making. If you need bulk clay for a group, Tomorotec’s 100-piece value pack is unbeatable for the price.
Whichever kit you choose, remember the basics. Condition your clay before shaping. Bake at the right temperature on parchment paper or a ceramic tile. Let pieces cool before handling. And keep your work sealed in plastic when you are not at the bench. Polymer clay rewards patience, and the right kit will keep you crafting happily for years.
