What Are Bioplastic Suncatchers?
At their core, these suncatchers are a sweet intersection of science and art. Made from a homemade, biodegradable plastic using ingredients like cornstarch, vinegar, and water, they’re tinted with food coloring and shaped into translucent designs that glow in the sunlight. Think melted candy glass—but safe and sustainable!

Ingredients You’ll Need
- ½ cup cornstarch
- 1 cup water
- 1 tablespoon glycerin (optional, makes suncatchers more flexible)
- 1 tablespoon vinegar
- Food coloring (optional, for color)
- Wax paper or parchment paper
- Pipettes, straws, or molds (optional for shapes)
- Spoon or craft stick (for stirring)
Tools You’ll Want on Hand
- A saucepan
- A flat surface for drying (like a baking sheet)
- Scissors (if cutting shapes later)
- String, yarn, or ribbon for hanging
- Craft knife or hole punch (optional for adding a hanging hole)
Optional Add-ins and Substitutions
- Use gel food coloring for more vivid shades
- Add eco-glitter for a sparkly finish
- Try essential oils for a lightly scented craft
- Skip the glycerin if you don’t need flexibility
- For extra shaping fun, try cookie cutters or pour into silicone molds
Step-by-Step Instructions
1. Mix Up Your Bioplastic
In a saucepan, whisk together:
- ½ cup cornstarch
- 1 cup water
- 1 tbsp vinegar
- 1 tbsp glycerin (optional)
Make sure everything is fully dissolved before heating.
2. Cook the Mixture
Place the pan over medium heat. Stir constantly as the mixture thickens. In just a few minutes, it’ll turn from liquid to a glossy, gel-like paste. Once thick and smooth, remove from heat.
3. Color Your Canvas
If you’re using color, now’s the time! Stir in a few drops of food coloring. You can even split the batch into small bowls to create multiple shades.
4. Shape Your Suncatchers
Lay out wax or parchment paper on a flat surface. Pour or spoon the mixture onto it and spread to desired thickness. You can use molds, cookie cutters, or straws to shape or design right in the goop!
5. Make Room for Hanging
Use a straw or toothpick to create a small hole near the top of each shape—this is where you’ll thread the string later.
6. Let It Dry
Let your creations dry for several hours or overnight. Dry time may vary based on humidity. They’ll be translucent, firm, and slightly rubbery when ready.
7. Trim, String, and Hang!
Once dry, peel them from the paper, cut into your desired shape if you haven’t already, and thread ribbon or string through the hole. Hang them in a sunny window and let the light dance!
Pro Tips & Variations
- 💎 Layer colors for a marbled look.
- 🌈 Pour into shaped silicone molds for stars, hearts, or even animal forms.
- ✂️ Cut out patterns with scissors once semi-set for crisp edges.
- 🌀 Add swirls of color using a toothpick before drying.
Storing Your Suncatchers
These are best displayed indoors and out of direct contact with water. They’ll last a few weeks to a few months depending on conditions. Keep in a cool, dry place when not in use. Compost them when they start to degrade—nature will thank you!
Frequently Asked Questions
Can I skip the glycerin?
Yes! Glycerin adds flexibility, but they’ll still work fine without it.
What if mine crack or curl while drying?
Try pressing them under a book or tray for a flatter finish.
Can I make them in advance?
Definitely. Just store them flat in a dry place until ready to hang.
Are they safe for young kids?
Yes! Just supervise around hot pans and sharp tools.
