Stenciling Crafty Tip
How to prepare a paper stencil for multiple uses? My favorite way to make a paper stencil last a long time and endure many paintings is to carefully run lines of packing tape over the front side of the stencil before you cut out the islands (openings). Be careful to have edges of tape overlay each other just a little to be sure that you have a good protective coating. It take s a little practice to avoid wrinkles and bubbles but you will get the hang of it soon.
Also, I prefer to cover only the front of the paper stencil with a layer of clear tape. Having a slick back will encourage paint to seep under the stencil.
