This 6 1/2" x 18 1/2" rectangle ruler features easy-to-read black and white markings printed in 1-inch grids marked in 1/8-inch and 1/4-inch increments. The ruler has a transparent textured fabric grip around all sides. 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 miscuts! Use the easy-to-read, black numbers (printed on white dots) and the 1/4" grip sides to cut whole inches. The 1/4 inch dashed lines printed on two adjoining sides aid in trimming seam allowances. Ruler is printed with 30, 45, and 60 degree lines for cutting angles, and has a QR code printed on it so you can scan it to view a tutorial showing how to use all the features of this versatile ruler.
