Materials (Ingredients)

• Clear shrink plastic sheets (brand name Shrinky Dinks or similar)
• Permanent markers (like Sharpies)
• Rubbing alcohol (99% isopropyl recommended)
• Cookie cutters (3″+ wide for traceable shapes)
• Scissors
• Eye dropper
• Single hole punch
• Aluminum foil
• Baking sheet
• Oven or toaster oven
• Spatula
• Split key ring with chain and jump ring
• Needle nose pliers

Necessary Tools

• Oven or toaster oven
• Parchment paper (optional alternative to foil)
• Protective gloves or spatula for flattening
• Heat-safe workspace

Ingredient Swaps and Additions

• Markers: Use alcohol inks for a more painterly, watercolor look.
• Plastic Sheets: Recycle #6 clear plastic containers (like salad boxes)—just clean and cut flat.
• Shapes: Instead of cookie cutters, print templates and trace them underneath the plastic.
• Decorations: Add metallic sharpies, glitter pens, or stickers before shrinking.
• Hooks: Turn these into bag tags, backpack charms, or zipper pulls with different hardware.

Step-by-Step Instructions

1. Trace Your Shape

Place a cookie cutter or paper template onto your shrink plastic and trace the outline with a gel pen or permanent marker. Choose shapes with bold outlines like hearts, stars, circles, or animals.

2. Cut the Shape

Use sharp scissors to cut out your traced shape. Smooth out any jagged edges.

3. Color with Markers

Color the shape with 3–4 different permanent markers. Fill most of the surface area, but don’t worry about being perfect—imperfections add to the tie-dye charm.

4. Add Rubbing Alcohol

Using an eye dropper, carefully drop rubbing alcohol onto the colored surface. The colors will start to blend and swirl. Add drops slowly and avoid over-soaking.

5. Let It Dry

Allow the piece to dry for at least 20 minutes. It should feel dry to the touch before baking.

6. Punch a Hole

Use a single hole punch to create a hole near the edge of your shape. This is where the keyring will go after baking.

7. Bake the Shape

Preheat your oven to 325°F (163°C). Place your shape on a foil-lined baking sheet. Bake for 1–3 minutes. The shape will curl up, then flatten. Once flat, let it sit 30 seconds before removing.

8. Flatten and Cool

If the shape isn’t completely flat, gently press it with a spatula while it’s still hot. Let it cool completely before touching further.

9. Assemble the Keychain

Use needle nose pliers to open the jump ring. Insert it into the punched hole, add the keychain chain, and close securely.

Pro Tips for Success

• Don’t over-soak with rubbing alcohol—it can make colors muddy.
• Use a silicone baking mat instead of foil to reduce static and sticking.
• If using recycled plastic, test a small piece in the oven first to check shrinkability.
• Color on the rough side of the plastic for better adhesion.
• Use fine-tip markers for detailed designs.

Serving Suggestions (Creative Uses)

• Use as backpack charms for kids.
• Make personalized gift tags that double as keepsakes.
• Create matching family keychains.
• Design themed sets for holidays or parties.
• String on twine to make colorful garlands.

Storing and Reheating

These keychains are durable and long-lasting, but here are a few care tips:

• Store in a dry, cool place away from direct sunlight to prevent fading.
• Wipe gently with a damp cloth to clean.
• Avoid bending or excessive pressure to maintain shape.

4. Are Shrinky Dinks safe for kids?
Yes, with adult supervision for baking and scissors. The shrinking process is safe and non-toxic.
