Whisk together the cornstarch and water in a small saucepan until smooth.

Place the saucepan over low heat and stir gently until the mixture becomes glossy and thick.

Once thickened, remove from heat and blend in the clear school glue until it’s fully combined. Optionally, add a tiny drop of food coloring or a sprinkle of glitter.

Arrange your pressed flowers inside the silicone molds and carefully spoon the warm mixture over them, smoothing the tops.

Allow the creations to dry completely for 24 to 48 hours.

Once dry, gently pop out the floral hearts and display them.
