Debby Brown, a well-known quilt teacher, developed this stencil to aid her when teaching her students how to free-motion quilt spirals. If you start out well, continuing the spiral is easy. That’s what these stencils are for. There are small ones for smaller, tighter spirals and larger ones when you want your spirals more open. Once you’ve traced the chalk line of the stencil you use the outermost line you just sewed as the guide to continue around and around until you want to stop.
