Create perfect 6-, 8-, or 10-in. finished Pineapple blocks by squaring up each round of strips as they are sewn. Since each round of strips is squared up before the next set is added, the blocks are perfectly square. The cutting requirements for the center square and the strips are printed right on the ruler. It comes with fully illustrated step by step instructions or scan the QR Code printed on the instructions to view a video demonstration. The ruler slides easily over the fabric until pressure is applied. Then, the Creative Grids exclusive gripper holds the fabric in place while cutting, eliminating slipping and miss-cuts!
