While going through notebooks from my bygone school days, I realized that the heavy plastic binder covers make the perfect material for durable patterns and templates. The plastic is easily cut with either scissors or razor blades, the templates hold their shape well through wet/dry cycles, and the thickness and rigidity make them ideal for tracing patterns. And if you need a larger pattern, join several pieces with duct tape.Besides plastic notebook covers, plastic signs, such as the type used for garage sales, also work well. When I have more than one template per project, I store the templates in a large manila envelope with the name of the project written across the front.—Dustin Davis, Cumberland, Md.
