How to Make DIY Eco-Friendly Suncatchers
-
Combine ingredients: In a saucepan, mix together cornstarch, water, glycerin, and vinegar. Stir well to create a smooth blend. This forms the base for your suncatchers-so ensure they're combined fully for the best results.
-
Heat the mixture: Place the saucepan over medium heat. Continuously stir the mixture as it heats until it thickens, which should take about 5 minutes. You'll know it's ready when it resembles a jelly-like consistency.
-
Cool slightly: Once thickened, remove the saucepan from the heat. Allow the mixture to cool for a few minutes, so it's safe to handle but still pliable for shaping.
-
Add color: If you wish to brighten your suncatchers, now is the time to add a few drops of food coloring. Mix thoroughly until the color is evenly distributed throughout the mixture.
-
Pour & spread: On a piece of wax paper or parchment paper, pour the mixture. Use a spatula or the back of a spoon to spread the mixture evenly to your desired thickness, typically around ¼ inch thick for the best effect.
-
Cut shapes (optional): If you want specific shapes, let the mixture set for a moment, then use scissors to cut it into your desired forms. Alternatively, you can leave it in a sheet for a more organic look.
-
Dry completely: Place the wax paper with the poured mixture on a flat surface, allowing it to dry for several hours or preferably overnight until completely firm and dry.
-
Punch holes: Once dry, use a craft knife or hole punch to create holes for stringing. This step is optional but adds a perfect touch for hanging your creations.
Optional: Try experimenting with glitter for a sparkling effect!

How to Store and Freeze DIY Eco-Friendly Suncatchers
Room Temperature: Keep your DIY eco-friendly suncatchers in a dry place away from direct sunlight, ensuring they last for several weeks without degrading.
Fridge: If you live in a humid environment, you can store the suncatchers in the fridge for up to 1 week, wrapped in tissue paper to absorb excess moisture.
Freezer: Freezing is not recommended, as it can compromise the integrity of your suncatchers, causing them to become brittle and lose their beautiful colors.
Reheating: If needed, simply allow them to return to room temperature before displaying again; avoid any direct heat as it may distort their shape.
DIY Bioplastic Variations
Feel free to let your creativity run wild and personalize these charming suncatchers to your heart's content!
-
Sparkle Boost: Add glitter to the mixture for a dazzling effect, creating suncatchers that shimmer in the sunlight.
-
Natural Colors: Instead of food coloring, use natural dyes from blended fruits or vegetables, like beet juice or spinach, to color your suncatchers, making them more eco-friendly.
-
Shape Play: Use cookie cutters or different molds to create unique shapes, turning your suncatchers into whimsical creations perfect for any occasion.
-
Layered Effect: Pour different colored layers into the mixture for a beautiful ombré effect; this adds depth and intrigue to your suncatchers.
-
Fragrant Touch: Incorporate a few drops of essential oils into the mixture, like lavender or citrus, for scented suncatchers that fill your space with a delightful aroma.
-
Textured Designs: Press dried flowers or leaves into the mixture before it sets to create beautiful, nature-inspired patterns.
-
Hanging Variations: Instead of string, use twine or yarn for a rustic touch when hanging your suncatchers, giving them a more organic feel.
-
Seasonal Twist: Change the colors and shapes according to the season-think pastels for spring or warm hues for fall-for decorations that celebrate nature's beauty all year round.
Expert Tips for DIY Suncatchers
-
Avoid Burning: Stir continuously while heating to prevent the mixture from sticking to the bottom or burning, ensuring smooth suncatchers.
-
Color Vibrancy: For vibrant DIY suncatchers, add more food coloring than you think you need; it often fades slightly as it dries.
-
Shape Variety: Use cookie cutters for uniform shapes or let kids freehand their designs; it adds a personal touch and makes crafting more fun.
-
Drying Location: Ensure the suncatchers dry in a warm, dry place to speed up the process and avoid moisture, which can ruin their texture.
-
Flexible Finish: If you used glycerin, your suncatchers will be more flexible; for a stiffer option, omit it, but keep them indoors to extend durability.

DIY Eco-Friendly Cornstarch Suncatchers Recipe FAQs
How do I know if my cornstarch is fresh?
Absolutely! When selecting cornstarch, check for a fresh, fine texture without any clumps or dark spots. If it has a musty smell or colors like yellow or brown, it may have gone bad and is better off replaced.
How should I store my finished suncatchers?
It's important to keep your DIY eco-friendly suncatchers in a dry place away from direct sunlight to avoid degradation. They can last for several weeks when stored properly in a cool, dry area. If humidity is a concern, consider wrapping them in tissue paper to help absorb excess moisture.
Can I freeze my suncatchers for long-term storage?
Very! Freezing is not recommended for these delicate crafts, as it may cause them to become brittle and lose their beautiful colors. Instead, store them at room temperature for the best results and always allow them to return to room temperature before displaying.
What should I do if my mixture doesn't thicken?
If your mixture isn't thickening, make sure you're stirring continuously while heating. This can take about 5 minutes. If it remains runny, it may need a bit more cornstarch; try mixing a tablespoon of cornstarch with a bit of water to create a slurry, then reincorporate it into your mixture and heat until thickened again.
What if I have allergies?
Make sure to check for allergies to any ingredients, especially if crafting with children. Cornstarch should be fine for most diets, but avoid food coloring if anyone is sensitive to certain dyes. Always confirm with any participants regarding potential allergenic reactions!
Can I use natural dyes instead of food coloring?
Absolutely! For a more organic approach, you can experiment with natural dyes derived from fruits and vegetables, such as beet juice for pink or spinach for green. Just remember that the colors may be softer compared to traditional food coloring, but they add a unique charm to your suncatchers!
