DIY Bioplastic Suncatcher Ingredients
• For the Mixture
- Cornstarch – Thickens the mixture to create a solid base for the suncatchers.
- Water – Acts as the solvent, crucial for mixing and dissolving the cornstarch; distilled water can enhance clarity.
- Glycerin (optional) – Adds flexibility to the suncatchers; can be omitted if unavailable.
- Vinegar – Helps with the consistency of the mixture and adds a subtle flavor if using food coloring; apple cider vinegar is a milder option.
• For Coloring
- Food Coloring (optional) – Brighten your creations with colors of your choosing; gel color works well for vibrant shades.
• For Drying and Shaping
- Wax paper or parchment paper – Provides a non-stick surface for easy drying; avoid wax paper if alternatives are available.
- Pan (saucepan) – Used for cooking the mixture to achieve the right consistency, any small saucepan will work.
- Flat surface (e.g., baking sheet) – Ensures even drying for your suncatchers; just use a clean, flat surface.
• For Cutting and Hanging
- Scissors – For cutting the suncatchers into fun shapes; a craft knife can create intricate designs if desired.
- String, yarn, or ribbon – Ideal for displaying the finished suncatchers; any durable string should suffice.
- Craft knife or hole punch (optional) – Use to make hanging holes if needed; this is optional if no holes are desired.

How to Make DIY Bioplastic Suncatchers
Combine ingredients: In a saucepan, mix ½ cup of cornstarch with 1 cup of water over medium heat. Stir gently to combine and ensure no lumps form.
Heat mixture: Continually stir as the mixture heats up. Watch closely until it thickens and turns translucent—this usually takes about 5-7 minutes. Remove from the heat.

Form shapes: Pour the colorful mixtures onto wax or parchment paper, spreading them evenly into fun shapes like hearts or stars.
Dry your creations: Allow the suncatchers to dry on a flat surface for several hours or overnight. They should feel firm and slightly pliable when ready.

DIY Bioplastic Suncatchers Recipe FAQs
What type of cornstarch should I use?
Absolutely! Make sure to use regular cornstarch and not corn flour or any other substitute. Cornstarch is the key ingredient that helps thicken the mixture, creating the right texture for your suncatchers.
How long can I store leftover suncatcher mixture in the fridge?
You can store any leftover mixture in a sealed container in the fridge for up to one week. Just ensure it's airtight to prevent it from drying out. When you’re ready to use it again, gently reheat over low heat while stirring until it returns to a workable consistency.
Can I freeze the completed suncatchers?
It’s best not to freeze the finished suncatchers, as this can cause them to become brittle. Instead, store them in a cool, dry place away from direct sunlight. If treated with care, they can last indefinitely!
What if my mixture is too lumpy?
If you notice lumps in your mixture, don't worry! It's crucial to stir continuously while cooking. If lumps form, you can try blending the mixture with a whisk or spatula once it thickens. If that doesn't work, you might need to start over with fresh ingredients.
Are these suncatchers safe for kids and pets?
Very! The ingredients used are non-toxic and safe for children, but avoid letting them ingest the mixtures, since they aren't food. Ensure you supervise younger kids during the crafting process, and keep the suncatchers out of pets' reach to prevent any chewing.
