CGRT225 22.5 Triangle
CGRT225 22.5 Degree Triangle Ruler from Creative Grids.
The ruler slides easily over the fabric until pressure is applied. Then, Creative Grids exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
Sew together 16 of these 22-1/2 degree triangles to create a complete circle; 8 to create a half-circle; or 4 to create a quarter-circle. Create Fans, Dresden Plates, etc. up to a finished size of 18 inches.
