Use this 18 degree circle segment ruler set to cut 20-petal round or pointed Dresden Plates from strips with no waste of fabric. Or sew together five segments to create round or pointed fans. Each petal can be cut up to 8-1/2 inches to create Dresden Plates us to 16-1/2 inches. A circle template for the center is included.
It comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration.
The ruler slides easily over the fabric until pressure is applied. Then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
