Lavish Swirls, from Prima's Kacha collection, casts one sweeping acanthus composition: mirrored leaf scrolls curling outward from a small shell-crowned oval frame at center. At 3 x 10 inches it's shaped for the places most moulds can't dress, aprons, headboards, door crowns and drawer spans.

The food-grade silicone mould pours 8 mm deep in paper clay, resin, air-dry clay, hot glue or chocolate. Cast it whole for a pediment-style crest, or trim the scrolls apart and let the pieces flow around corners.
