How to Make DIY Bioplastic Suncatchers

Combine Ingredients: In a saucepan, mix cornstarch, water, vinegar, and glycerin (if using). Stir well until the mixture is smooth and free of lumps—this will be your magical base.
Heat the Mixture: Place the saucepan over medium heat, and stir constantly. Watch closely as the mixture begins to thicken in about 10 minutes; it should turn into a gel-like consistency.
Cool Slightly: Once thickened, remove the saucepan from the heat, and let it cool for a few minutes. Knowing how and when to cool this mixture is key for the next steps to shine!
Add Color: Stir in your chosen food coloring until it is fully blended. This is where your creativity can flourish, so don’t hold back!
Spread the Mixture: Pour the colorful mixture onto wax or parchment paper, spreading it gently to about ½ inch thick. Use a spatula or the back of a spoon for even spreading.
Shape Your Art: While the mixture is still wet, shape it as desired. Use cookie cutters or your hands to create fun designs, and then let it dry completely—this can take several hours to overnight.
Cut Out Shapes: Once the suncatchers are dry, carefully cut out the shapes using scissors. If you want to hang them, use a craft knife or hole punch to create holes, adding a little flair.
Hang and Enjoy: Thread string, yarn, or ribbon through the holes and display them in sunny windows. Sit back and watch as the light transforms your art into a magical wonderland!

Optional: Add glitter to the mixture before spreading for extra sparkle!

Make Ahead Options

These DIY Bioplastic Suncatchers are perfect for busy home cooks looking to save time during the week! You can prepare the cornstarch mixture up to 24 hours in advance by following steps 1-4, then refrigerate it in an airtight container to maintain its quality.

After spreading the mixture and cutting out shapes, leave the suncatchers to dry completely for several hours to overnight, ensuring they’re ready to catch the sunlight. This way, you can enjoy making beautiful crafts without the rush, bringing cheer to your home!

DIY Bioplastic Suncatchers Recipe FAQs

How do I choose the right cornstarch for this recipe?
Absolutely! When selecting cornstarch, look for brands that are pure, without any additives or anti-caking agents. The texture should be fine and powdery. Most regular grocery store brands work perfectly.

What is the best way to store the finished suncatchers?
To store your DIY Bioplastic Suncatchers, keep them in a cool and dry place, away from direct sunlight. This prevents fading and maintains their vibrancy. Ideally, a closed container or zip-top bag for flat designs is perfect. They can last anywhere from a few weeks to several months if cared for properly.

Can I freeze my suncatchers to extend their shelf life?

What can I do if my mixture burns on the stove?
If the mixture begins to burn, it can affect the texture and the final result. Remove the pan from the heat immediately, and let it cool. If the mixture has solidified or has a burnt taste, it’s best to start over to ensure your suncatchers turn out beautifully.
