All of these are wonderful methods.. I have purchased the template plastic from the craft store and used ti to make a master copy....it doesn't scorch and holds its shape. I then put it in a folder for future use on another project and incorporate freezer paper and cardboard or other plastics, even newspaper to make the multiple shapes for new quilts. I build a template stash this way and allow myself plenty of options for future designs on the many quilts I have yet to make.
