THE LARGEST SQUARE UP RULER AVAILABLE TO QUILTERS. THIS RULER IS PERFECT FOR CUTTING 22" MEDALLIONS, SQUARING UP QUILT CORNERS, AND GENERALLY CUTTING AND SQUARING UP LARGE BLOCKS. ELIMINATES THE NEED TO DOUBLE FOLD FABRIC FOR FUL WIDTH CUTS. PROVIDES BETTER STABILITY FOR THOS LONGER CUTS THAN A NARROW RULLER.
