Thanks Barb for your reply. I printed out the Sawtooth pattern from Quilters cache. It is for a 12" block. But the fabric I want to use has a bigger print, so would look better if the center square is cut out at 9 1/2". Her pattern for the star , the center is cut out at 6 1/2". I need to know what measurements to make the corners and other edges. I did try doubling the measurements, but that would end up being a 24" star block , and I think it would look too big.
