Remember those magical plastic sheets from childhood? The ones you’d draw on, pop in the oven, and watch shrink down into tiny, hard treasures? That retro craft, often known by the brand name Shrinky Dinks, is back and bigger (well, smaller, technically!) than ever. Shrink plastic, or shrink film, is an incredibly versatile, affordable, and downright fun material that opens up a world of creative possibilities for crafters of all ages and skill levels. Whether you’re looking to make personalized gifts, unique accessories, or just have a fun afternoon crafting, these shrink plastic ideas are sure to inspire you. Get ready to unlock the magic of shrinking!
What is This Magical Shrinking Stuff, Anyway?
At its core, shrink plastic is a special type of polystyrene plastic sheet (#6 plastic is the key ingredient, which is why some people experiment with recycled containers!). These sheets are designed specifically to shrink dramatically – often down to between 1/3 and 1/2 of their original size – and become significantly thicker and harder when heated consistently, typically in an oven.
It comes in various forms to suit different projects:
- Clear: Perfect for traced designs or when you want a see-through effect.
- Frosted/Matte: Has a slightly rough surface, ideal for using colored pencils or chalk, resulting in a softer, less glossy finish.
- White/Black/Colors: Opaque sheets that provide a solid background color.
- Inkjet Printable: Specially coated sheets that allow you to print designs or photos directly from your computer!
The shrinking process itself is fascinating to watch. As the plastic heats up, it will curl, twist, and contort before eventually flattening out into its final, shrunken form.
Gearing Up: Your Shrink Plastic Crafting Kit
Getting started with shrink plastic is relatively simple and doesn’t require a huge investment. Here’s what you’ll need:
The Essentials:
- Shrink Plastic Sheets: Choose the type that best suits your project (clear, frosted, printable, etc.).
- Coloring Tools:
- Permanent Markers (like Sharpies): Best for smooth, clear, or colored plastic. Bold and vibrant.
- Colored Pencils: Excellent for frosted or sanded plastic, allowing for blending and shading.
- Paint Pens (Acrylic): Offer opaque coverage, good for bold designs.
- Inkjet Printer: Only for use with specifically marked “Inkjet Printable” shrink film.
- Scissors: Sharp scissors are needed for clean cuts. Small, precision scissors are great for detailed work.
- Hole Punch: A standard office hole punch is perfect for creating holes for keychains, jewelry, or tags before you bake.
- Oven: A conventional oven or a toaster oven works perfectly. Do NOT use a microwave oven.
- Baking Sheet: Any flat baking tray will do.
- Liner: Parchment paper, a piece of brown paper bag, or medium-weight cardboard to place on your baking sheet. This prevents sticking and protects your tray.
- Oven Mitts: Safety first!
- Flat Object: A metal spatula, a thick book covered in paper, or a smooth block of wood to gently flatten pieces immediately after baking if needed.
Nice-to-Haves:
- Heat Gun/Embossing Tool: An alternative to an oven, allowing for more targeted heating, but requires practice to get even results. Not suitable for large pieces.
- Fine-Grit Sandpaper: Useful for lightly roughing up clear plastic so colored pencils or chalk will adhere better.
- Sealant: Clear acrylic spray sealer (like Krylon Crystal Clear), Mod Podge (apply thin coats), or UV resin for a super glossy, durable finish.
- Jewelry Findings: Jump rings, earring hooks/posts, necklace chains, pin backs, keychain rings, lobster clasps.
- Strong Glue: E6000 or a similar strong craft adhesive suitable for plastic and metal is needed for attaching findings like pin backs or magnets.
Unleash Your Creativity: Awesome Shrink Plastic Ideas
Now for the fun part! Here are just some of the amazing things you can create with shrink plastic:
Dazzling DIY Jewelry
Shrink plastic is absolutely perfect for creating lightweight, custom jewelry pieces. Think unique earrings – tiny studs featuring miniature drawings, intricate dangling designs, or even abstract shapes. Craft personalized pendants for necklaces with initials, symbols, or tiny replicas of your favorite things. You can also make adorable charms for bracelets. Get creative by layering shrunk pieces for a 3D effect or mixing clear and frosted elements. Use inkjet sheets to make tiny photo pendants! Remember to punch holes for jump rings before baking and seal your finished pieces to protect them from scratches and moisture.
Personalized Keychains and Bag Tags
Say goodbye to boring keychains! Shrink plastic lets you design tags that truly reflect your personality or make fantastic personalized gifts. Create keychains featuring names, favorite cartoon characters, pet portraits (printable film is great here!), inspiring quotes, or logos from your favorite fandoms. These also make brilliant, durable tags for backpacks, luggage, or gym bags. Choose a sturdy shrink film, punch a hole for the ring or clasp before shrinking, and consider adding extra flair like small beads or tassels to the metal ring.
Unique Pins and Badges
Add some personality (or “flair”!) to your denim jacket, tote bag, hat, or bulletin board with custom-made pins. Shrink plastic is ideal for creating small, detailed badges. Design pins featuring inside jokes, cute illustrations, miniature versions of your artwork, band logos, or awareness ribbons. After designing, cutting, and shrinking your piece, simply use strong craft glue (like E6000) to securely attach a metal pin back. Frosted or white shrink plastic often works well for pins, giving them a slightly more subtle, less glossy look unless you choose to seal them with resin.
Cute and Custom Magnets
Brighten up your refrigerator, locker, or office whiteboard with handmade magnets. This is a fantastic project for using up smaller scraps of shrink plastic. Create miniature food items (tiny donuts, fruit slices), alphabet letters for kids to play with, small floral designs, funny faces, or even tiny reminder notes. Ensure your design shrinks completely flat, let it cool thoroughly, and then glue a small, strong craft magnet (or two for larger pieces) onto the back.
Charming Wine Glass Charms
Never mix up your drinks at a party again! Create sets of themed wine glass charms using shrink plastic. Think tiny fruits, different colored geometric shapes, seasonal icons (snowflakes, leaves, flowers), or even guests’ initials. Keep the designs relatively small and lightweight. Punch a hole near the edge before baking. Once shrunk and cooled, attach a simple hoop earring finding or a specialized wine charm ring through the hole. These make lovely hostess gifts too!
Garden and Plant Markers
Add a touch of durable, waterproof personality to your indoor or outdoor plants. Label your herbs, vegetables, flowers, or succulents with custom markers. You can write the plant name clearly with a permanent marker, draw a small picture of the plant, or create fun, decorative shapes. Make sure to use markers that can withstand moisture and sunlight, and sealing the finished piece is highly recommended for outdoor use. Either punch a hole to tie the marker onto a stake or design the marker with a long “stem” that can be pushed directly into the soil (seal this part well!).
Handmade Gift Tags
Elevate your gift-wrapping game with reusable, handmade gift tags. Instead of disposable paper tags, create durable and charming tags from shrink plastic. Shape them like classic tags, circles, stars, holiday ornaments, or even miniature versions related to the gift (like a tiny book shape for a book present). Punch a hole for tying with ribbon or twine. You can leave space to write “To/From” on the back with a permanent marker after shrinking, or incorporate it into the design itself.
Festive Ornaments
Shrink plastic is fantastic for creating custom ornaments for any holiday or just for everyday decoration. Design snowflakes, spooky ghosts, Easter eggs, colorful flowers, tiny animal figures, or even miniature family portraits using inkjet printable sheets. Add glitter glue or metallic markers before shrinking for extra sparkle. Remember to punch a hole for hanging with ribbon or an ornament hook. These are lightweight and less likely to break than glass ornaments, making them great for homes with kids or pets.
Fun Zipper Pulls
Make zippers on coats, backpacks, purses, or pencil cases easier to grab and add a pop of personality with custom zipper pulls. Small, sturdy designs work best. Think tiny monsters, initials, sports balls, or favorite symbols. The process is similar to making keychains, just on a smaller scale. Punch a hole, shrink your design, and attach it to the zipper using a small lobster clasp, a loop of strong cord, or a small metal ring.
Scrapbooking and Card Making Embellishments
Add unique, dimensional flair to your paper craft projects. Shrink plastic allows you to create custom embellishments that stand out. Make tiny flowers, individual letters or words, themed shapes (hearts, stars, arrows), miniature frames for tiny photos, or any small icon that fits your scrapbook layout or handmade card design. These add texture and visual interest. Keep them relatively flat for easier adhesion, and use a strong liquid glue or glue dots to attach them securely.
Engaging Kids’ Crafts
Shrink plastic is a guaranteed hit with kids (just make sure an adult handles the oven part!). It’s a magical process for them to witness. Let them unleash their creativity by drawing their favorite characters, simple shapes, colorful monsters, or tracing their own hands (remind them to draw large!). Frosted shrink film combined with colored pencils is often easiest for little hands. The finished pieces can become keychains, magnets, or simply treasured keepsakes. It’s a perfect rainy-day activity or a fun craft for a birthday party.
Beyond the Basics: Advanced Techniques
Once you’ve mastered the basics, there’s more to explore! Try layering multiple shrunk pieces with foam dots or strong glue to create cool 3D effects. Carefully use a heat gun (with gloves and caution!) to gently shape the plastic as it cools – you can make rings or slightly curved shapes (this takes practice!). Some crafters even press the warm, pliable plastic into heat-resistant silicone molds for specific shapes. Experiment with combining shrunk pieces with other craft materials like UV resin (for doming or embedding glitter), wire wrapping, or beads.
Tips for Shrink Plastic Success: Avoiding Pitfalls
While shrink plastic is fun, a few tips can help ensure your projects turn out great:
- Color Intensity: Remember that colors will darken and become much more intense after shrinking. Always color lighter than you want the final result to be. Test colors on a scrap piece first if unsure. Let marker ink dry completely before handling or baking to avoid smudges.
- Cut and Punch First: Do all your cutting and hole punching before you bake. The plastic becomes hard and brittle afterwards, making it difficult (and risky) to cut or punch.
- Baking Basics: Follow the temperature and time guidelines on your specific shrink plastic package (usually 130°C-175°C / 275°F-350°F for 1-3 minutes). Preheat your oven. Place pieces colored-side up on your lined baking sheet, giving them some space. Crucially, watch them bake. They need to go through the curling phase and then flatten out. Remove them promptly once they are flat.
- Flattening Fix: If your pieces come out slightly curved or bumpy, act fast! While they are still hot and pliable (use oven mitts and/or a spatula), immediately press them gently with a flat, smooth object (like the bottom of a glass, a book protected with paper, or a woodblock) for a few seconds until flat.
- Curling Catastrophes: Sometimes pieces curl and touch themselves, sticking together. If this happens, quickly take the tray out, use tweezers or toothpicks to gently pry the stuck parts apart (be careful!), and pop it back in the oven to finish shrinking. Placing a piece of parchment paper on top of your designs while baking can sometimes help minimize extreme curling.
- To Seal or Not to Seal?: Sealing isn’t always necessary, but it’s highly recommended for items that will be handled frequently (like jewelry, keychains, magnets) or exposed to moisture. It protects the color, prevents scratches, and adds durability. Clear acrylic spray, thin layers of Mod Podge, or a coat of UV resin are popular choices. Let your piece cool completely before sealing.
- Size Matters: Don’t forget the shrink factor! Your final piece will be significantly smaller (around 40-50% of the original size) and much thicker. Draw or print your initial designs large enough to compensate. Very large, intricate pieces are more prone to uneven shrinking or distortion.

People Also Ask (FAQs) About Shrink Plastic
- What is the best thing to draw on shrink plastic with? For smooth/clear plastic, permanent markers (like Sharpies) are best. For frosted or sanded plastic, colored pencils work beautifully, allowing shading. Acrylic paint pens also work well. For specially coated sheets, an inkjet printer can be used.
- How much does shrink plastic actually shrink? It typically shrinks to about 40-50% of its original linear dimensions (meaning about 1/4 to 1/5 of its original area) and becomes roughly 6-9 times thicker. Check the packaging for specifics, as brands can vary slightly.
- Why did my shrink plastic curl up and stay curled? This usually happens if it’s removed from the oven too soon before it has fully flattened, if the oven temperature was too low or uneven, or if it wasn’t flattened immediately after removal while still hot. Try baking slightly longer or ensuring you flatten it right away.
- Can you use regular plastic (#6 recycling symbol) for shrink crafts? Yes, clear #6 plastic (often found in takeout containers or bakery boxes) can work. Clean it thoroughly and be aware that results might be less consistent than purpose-made shrink film. It may shrink differently or become cloudier. Always test a small piece first.
- Do you need to seal shrink plastic? It’s not mandatory, but highly recommended for durability, especially for items like keychains, jewelry, or magnets that get handled often. Sealing protects the artwork from scratches, wear, and moisture. Popular sealants include clear acrylic spray, Mod Podge, or UV resin for a glossy finish.
- What temperature do you bake shrink plastic at? Temperatures generally range from 130°C to 175°C (275°F to 350°F). However, always check the specific instructions on the packaging of the shrink plastic you are using, as recommendations can vary between brands and types.
