Each set contains 4 stencils and one masking piece. The masking piece keeps the text areas free from background patterns. Each stencil can be used on its own or with others in the set. Messages and frames can be mixed and matched with backgrounds from other sets. All stencils work with royal icing and airbrush. All stencil sets fit most 3-4" plaque cutters. Instructions included on how to use the stencils to create a layered look. Each stencil is made from 10 mil food-grade mylar. Made in the USA. Cookies and photos by Julia M Usher.
