I'm all for shortcuts when cutting fabric, but there are a lot of rulers, which are somewhat like templates that make our lives easier. I once bought a set of double wedding ring plastic templates for rotary cutters from Shar Jorgensen, which I liked. I never did get around to making that quilt, although I wanted to and somehow in the move from a house to an apt. they vanished. I'll have to find another way I guess, to make that particular quilt.
