Ruler - Precision Trimmer 3
Low in-store inventory, may be subject to change.
This 3-1/2" square ruler was designed by Marsha McCloskey to measure from the center. Make extremely accurate 4-triangle squares by first cutting the triangles larger than they need to be, then stitching the triangles to make a square. Center the Precision Trimmer 3 on the sewn unit and trim the edges to the perfect size.
