Ingredients Method Notes

Ingredients
  

  • Cornstarch 1 cup
  • Distilled water 1 cup
  • White vinegar 1 tablespoon
  • Glycerin 1 teaspoon, optional
  • Food coloring or natural pigments small drops or powders, optional
  • Small silicone molds or cookie cutters
  • Nonstick baking mat or parchment paper
  • A small saucepan and a wooden spoon
  • Measuring spoons and cups
  • Thin string fishing line, or flexible wire
  • Small dried flowers leaves, or translucent paper (optional embellishments)
  • Scissors and a hole punch or a small skewer

Method
 

  1. Gather everything and set up a calm workspace with good light.
  2. Mix cornstarch and water in the saucepan.
  3. Stir slowly until the mixture looks smooth and slightly milky.
  4. Add the vinegar and glycerin, and watch the liquid settle.
  5. Heat the mixture over low to medium heat, stirring constantly.
  6. Remove from heat when it becomes glossy and pulls together.
  7. Add color or pigments now, folding them in with smooth strokes.
  8. Spoon or press the warm bioplastic into molds or onto parchment.
  9. Make a small hole for hanging while the piece is still soft.
  10. Let the suncatcher dry slowly at room temperature for 24 to 72 hours.
  11. Trim edges and thread string once dry.

Notes

Glycerin is optional but helpful for a softer finished piece. Use silicone molds for even shapes, or work freeform on parchment for organic pieces. Store finished suncatchers flat and away from direct sunlight.
