Plastic molds are available through several craft supply retail outlets, as well as many websites that offer supplies relating to crafts and do-it-yourself projects. Michaels, Hobby Lobby, Jo-Ann Fabric and Craft Stores, and Walmart all have plastic molds available for in-store purchase.
Plastic molds are also available for purchase online at sites such as Amazon.com, Etsy and eBay. Craft enthusiasts use plastic molds for a variety of projects, such as making plaster shapes, clay beads, soaps, candles, and edible creations such as chocolate candies or fondant decorations for cakes. When filled with water, plastic molds can also produce decoratively shaped ice.
