This multi-sized ruler features the two triangles required to complete a flying geese unit - 45 and 90 degree - in one tool. Cut flying geese units up to a finished size of 6 inches x 12 inches. Or, use the triangles individually to cut half-square triangles up to a finished size of 6 inches and cut quarter-square triangles up to a finished size of 12 inches. The math required to cut these angles is incorporated into the easy to read black and white markings.

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!
