By designer Rachel Cross, this quilting ruler is simple to read and use. This Multi-Size 2 peaks in 1 triangle combines the angles you need to create triangles in a square block. The keyhole cut-out allows you to cut both angles with one tool. The tall center triangle is used to cut strips measuring 1-1/2' to 6-1/2" with no waste. Cut side triangles with the other triangle on the ruler. Equipped with Creative Grid's exclusive grip, this 13" x 7" ruler slides easily on fabric yet stays in place when pressure is applied. The ruler comes with fully illustrated step by step instructions or scan the QR Code printed on the ruler to view a video demonstration of these features. Made in the USA.
