Learning the alphabet is a fundamental part of education, just like squares are literally a basic building block of quilting. The GO! Square 2" makes quick and precise squares even through multiple layers of fabric. It finishes to a 1 1/2" square ideal for cornerstones, watercolor quilts, checkerboard designs, scrappy quilts, prairie points, 4-patch and 9-patch blocks and borders. As easy as A-B-C! Can be used on GO! Me. GO! Baby, GO!, GO! Big, and GO! Studio.
