Make Cats Cradle units quickly, easily and accurately, two at a time from squares and rectangles. You never cut a single triangle, but with the Cats Cradle tool you end up with perfect triangles in your finished blocks every time. Create six sizes from 1 1/2 to 4 inch finished blocks - the cutting requirements for each is printed right on the ruler! The ruler comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration. The ruler slides easily over the fabric until pressure is applied. Then the exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts! Total Size - 7in x 7in Creative Grids® products are made in the USA and sold in independent quilt shops only.
