Ingredients
- Cornstarch, plain
- Water, room temperature
- Vegetable oil (1 tsp per cup of cornstarch)
- Vinegar or lemon juice (optional)
- Dried flowers or pressed petals
- Nonstick baking paper or silicone mat
- Small saucepan
- Wooden spoon or silicone spatula

Instructions
- Measure and combine cornstarch with water in a saucepan, adding oil and vinegar if using.
- Warm the mixture slowly over low heat, stirring with a wooden spoon until thick.
- Reach a thick, pudding-like consistency, then remove from heat.
- Knead the warm dough in a bowl lined with baking paper until smooth.
- Flatten the dough between sheets of baking paper to an even thickness.
- Arrange dried flowers on the bioplastic and gently press them into the surface.
- Seal the flowers with a top sheet and cut shapes while the material is warm.
- Dry the pieces at room temperature until firm, flipping occasionally.
- Finish by smoothing edges with a damp sponge once dry.
Notes
Cornstarch adds firmness; oil keeps the mixture soft. Use fully dried petals to avoid moisture. Store pieces flat to preserve form.
