In Rulers & Accessories DESCRIPTION The Stripology Squared, a slotted ruler by Gudrun Erla, has cutting slits every 1/2 inch so each strip you cut is the exact same size EVERY time! Follow the easy-to-read markings: squares for 2-1/2 inch cuts and stars for 1-1/2 inch cuts - no math required! Cut five 2-1/2 or eight 1-1/2 inch strips without ever moving the ruler. The Stripology Squared includes markings to square up half-square triangles, quarter-square triangles, and blocks in whole and half inch increments up to 12-1/2 inches. 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! This ruler comes with fully illustrated step by step instructions or watch Gudrun's video tutorial. The Stripology Squared Ruler is the perfect size to take to classes and retreats. This ruler is also available in a smaller size - the Stripology Squared Mini (Item CGRGE3).
