Perfect for detailed projects that require layers of color. The clear, matte finish is great for tracing and works well with a light box. Simply peel off the backing, adhere to an image that is on scrap paper, cut out the image, peel off the Mask It and place it over the like image on the final crafting surface. The image can then be given a background effect by spraying with inks, etc. Remove the reusable Mask It image, and it's done!
