I use plastic folders to make patterns for English Paper Piecing. Instead of making piles of patterns out of card stock, I only need to make a few of these and use them over and over again. Trace the pattern, cut it out, and punch a hole in the center. Then fold the fabric over the plastic template, and take a stitch at each corner. To remove the template, insert an orange stick or small dowel into the hole, and pull up until the plastic piece comes loose.
