The Clover 9579 No-Hassle Triangle Gauge allows you to effortlessly cut, mark, and stitch to create 1/2 -square or 1/4- square triangle blocks without ever cutting triangles or guessing at the sizes.
Use No-Hassle Gauge to make 5 block sizes for both 1/2- and 1/4- square triangles. Create 2-1/2" (64mm), 3-1/2" (89mm), 4-1/2" (114mm), 5-1/2" (140mm) and 6-1/2" (165mm). Reference the left side of the gauge for 1/2-square triangles and the right side for 1/4-square triangles. The sliding gauge locks for accuracy.
