1 cup cornstarch
1 cup baking soda
¾ cup water
Small dried or pressed flowers
Silicone heart molds
Silicone flower molds, if desired
Small saucepan
Mixing spoon or spatula
Measuring cups
Clear craft sealer, optional
Ribbon or twine, optional
Instructions
Combine the cornstarch, baking soda, and water in a saucepan. Stir well until the mixture is smooth and free of lumps.
Place the saucepan over low to medium-low heat and stir continuously. As the mixture heats, it will gradually thicken. Continue stirring until it forms a soft dough-like consistency and begins pulling away from the sides of the pan.
Remove from the heat and allow the mixture to cool until it is comfortable to handle. Knead it gently until smooth. If it is too sticky, add a small amount of cornstarch.
Place your silicone molds on a flat tray. Arrange small dried flowers inside each heart or flower mold. You can use daisies, violets, baby’s breath, lavender, small petals, or tiny leaves.
Carefully press the cooled mixture into the molds around the flowers. Fill the molds evenly and gently press the mixture into the corners. Avoid pressing too hard, as delicate flowers can break.
Smooth the surface with your fingers or a small spatula.
Leave the filled molds in a clean, dry, well-ventilated area. Allow the pieces to dry completely. Depending on their thickness and the humidity, drying can take 24 to 48 hours or longer.
Do not remove the hearts from the molds until they are completely firm. Once dry, gently flex the silicone mold and release each piece.
For a glossy, glass-like appearance, apply a suitable clear craft sealer after the pieces have dried completely. Apply thin coats and allow each coat to dry according to the product instructions.
If you want to turn the hearts into ornaments, make a small hole near the top while the material is still workable. Once completely dry, thread ribbon or twine through the hole.
These floral hearts make beautiful decorations, gifts, wedding keepsakes, memorial keepsakes, garden souvenirs, or seasonal ornaments.
For the prettiest results, use completely dry flowers, avoid overcrowding the molds, keep the pieces a fairly even thickness, and allow plenty of time for them to dry before removing or sealing them.
