The Maxi Molds are a flexible, durable and washable mold with detailed designs that coordinate with the paper collections. They make beautiful decorations that can be finished with a variety of paints and waxes. To make the mold, you can use soft clay, ceramic powder, two part resin or fimo. You cannot use hot glue in these molds! The depth of the mold varies by design, but these are larger molds. An idea for you would be to use a resin and when set, paint and add a magnet! These are perfect for all types of mixed media projects. Size 8x11"
