How to Make Bioplastic Suncatchers DIY
Combine Ingredients: In a saucepan, mix the cornstarch and water together. Stir continuously over medium heat until the cornstarch completely dissolves to avoid any annoying lumps in your mixture.
Add Shine: Next, incorporate the glycerin and vinegar into the saucepan. Cook while stirring constantly until the mixture begins to thicken—this usually takes just a few minutes.
Cool Down: After thickening, remove the saucepan from heat and let it cool slightly. This will make it easier to handle when you’re ready to pour it into shapes.
Color it Up: Divide the cooled mixture into separate bowls. Add natural food coloring to each one, adjusting the intensity as desired. Stir until the colors are bright and well-blended.
Shape it Out: Pour the colorful mixture into cookie cutter shapes placed on a wax paper-lined tray. Create fun designs and layers for added interest!
Drying Time: Allow the shapes to dry for several hours until they are solid. If you're in a hurry, you can place them in a low-temperature oven to speed up the drying process.
Display Your Art: Once fully dried, gently remove the suncatchers from the tray. Hang them in windows or on porches to invite vibrant light into your space.
Optional: Add glitter to your mixture for an extra sparkle effect!

Bioplastic Suncatchers DIY Recipe FAQs
What type of cornstarch should I use for the suncatchers?
Absolutely! Use regular cornstarch, as it provides the right structure for your bioplastic suncatchers. Look for a brand that is pure and doesn’t contain any additives to ensure a smooth mixture.
What’s the best way to store any leftover mixture?
The more the merrier! Store any unused mixture in an airtight container in the fridge for up to one week. Just let it come back to room temperature before you’re ready to create again – a little shake or stir will help reintroduce the ingredients.
Can I freeze the prepared mixture?
Yes, you can! To freeze the mixture, pour it into an airtight container, ensuring there is minimal air inside. It can be frozen for up to three months. When you’re ready to use it, simply thaw it in the fridge overnight, then give it a good mix before pouring into shapes.
What should I do if my suncatchers come out lumpy?
No worries! If lumps appear, that's often due to cornstarch not being fully dissolved. To remedy this, whisk the mixture while heating to ensure everything blends smoothly. If lumps persist upon cooling, you can blend it lightly in a food processor to achieve a uniform texture.
Are these suncatchers safe for pets and kids?
Very much so! The ingredients are non-toxic and safe for both kids and pets. However, I recommend supervising younger children while crafting, just to avoid any accidental ingesting of materials.
What’s the best way to hang the suncatchers?
You can use clear fishing line or transparent ribbon to hang your suncatchers in windows. Simply poke a small hole in the top of the dried shape and tie it securely. This way, they’ll dance beautifully in the light while looking stunning from both inside and outside your home.
