Sew together 24 of these 15 degree triangles to create a complete circle; 12 to create a half-circle; or 6 to create a quarter-circle. Create Fans, Dresden Plates, etc. up to a finished size of 48 inches. Total ruler length is 24.5".
Use the vertical lines to fussy cut stripes or cut half triangles (the 1/4 inch seam allowance is marked). Or cut 30; 45; 60; and 90 degree units with the angles marked on the ruler.
The ruler slides easily over the fabric until pressure is applied. Then, an exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
The ruler comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration.
