Use the straight side of this single strip ruler to cut 1-1/2 and 2-1/2 inch strips – or use the pre-cuts that are on the market. Sew these strips together to create a 2-1/2 inch wide strip set. Turn-a-Round the ruler to cut nine tumblers that finish 2 inches. Multiple layers can be cut at one time. The key holes in the ruler enable the rotary cutter to cut the sides without damaging the ruler. The ruler slides easily over the fabric until pressure is applied. Then, our exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts! It comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration. Creative Grids Rulers have a MAP (Minimum Advertised Pricing) Policy.
