Create a complete circle when you sew together 16 of these 22-1/2 degree triangles! Eight will create a half-circle and 4 creates a quarter circle giving you lots of design options like Fans, Dresden Plates and more.
 
The verticle line can be used to fussy cut stripes or cut half triangles and the angled lines will create intricate blocks. The quilt ruler includes .25 inch seam allowances.
 
Easily slide the ruler over the fabric until pressure is applied and the Creative Grids exclusive grip holds the fabric in place while cutting, eliminating slipping and miss-cuts!
