Stripology Squared has all of the features you love in the original Stripology ruler, and it will make 'squaring up' a breeze! The smaller size is easier to manipulate and is more portable so it is the perfect choice when traveling to classes and retreats. Follow the easy-to-read markings - squares for 2" cuts, and stars for 1" cuts - no math required! Stripology Squared includes markings to square up half-square triangles, quarter-square triangles, and blocks up to 12". And, since the slots are longer to accommodate larger blocks, it is the perfect choice for cutting wider fabrics. 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! Dimensions of ruler are 14.75" x 18".
