Step 5: Drying
- Carefully transfer the shapes onto a baking sheet lined with parchment paper.
- Allow them to dry for 24-48 hours in a cool, dry area.
Step 6: Finish Up
- Once completely dry, carefully peel the suncatchers off the parchment paper.

Tips & Variations:
- Experiment with different food coloring combinations for unique shades.

Frequently Asked Questions:
1. Can I use regular plastic wrap instead of clear plastic wrap?
Yes, regular plastic wrap works as long as it’s durable enough to hold the mixture without tearing.
2. What can I use if I don’t have cornstarch?
You can try using arrowroot or tapioca starch, but the texture may vary slightly.
3. How can I store leftover bioplastic mixture?
Store any leftover mixture in an airtight container in the refrigerator for up to a week.
4. What if the suncatchers are too sticky after drying?
If they are sticky, they may need more drying time or should be dusted lightly with cornstarch.
Suggestions:
- Use your suncatchers as gifts for family and friends.
- Hang them on your porch or in your garden to attract butterflies.
- Create a theme for seasonal decorations, like autumn leaves or winter snowflakes.
