Stencils are like stickers where the gift keeps on giving. Made of 14 ml Mylar they offer flexibility to use on both flat and curved surfaces while still being durable for repeat use. Can tape on for quick action or use a temporary adhesive backing to get really clean line results. Stencil art size is about 6.5 X 7. If you have a little patience, you can even mix it up with mulitple colors by manually masking.
