This square cutting ruler set was designed by Lori Holt of Bee In My Bonnet and is perfect for cutting and squaring up quilt blocks sized 2 1/2", 3 1/2", 4 1/2", 5 1/2" and 6 1/2" square. Measurements as small as 1/8" and are perfect for quilting and general use. One great feature is that the underside of each ruler has it's own texture for easier fabric gripping... not to mention, it will look so cute in your sewing room!
