If you're like me, you probably have a few patterns that you use over and over, til they fall apart. I solved the problem by using clear contact paper. Cut pattern apart. Place contact paper with backing side UP. Peel enough of backing off to place pattern piece on it. Carefully place pattern piece on contact paper. Can be either side up, sometimes I cover both sides, if it's a real favorite! Patterns will last a long time, and won't rip or wear out so fast.

For any craft that has a "paper" pattern that has to be pinned/taped down (especially sewing patterns), transfer/cut them out onto contact paper.
