The coordinating mask stencils are designed to work perfectly with Altenew\'s stamp sets! These handy mask stencils are made out of a thinner material than our regular stencils so you can easily stamp over them, or use with your favourite colouring mediums! Position the positive cut pieces over their coordinating images with a bit of temporary adhesive, then stamp over with another image. When you remove the stencil, it will look like the second image is behind the first!Specification Size: 6in x 6in Made in the USA
