Creative Grids Starburst 30 Degree Triangle Quilt Ruler (CGRISE30)

Sew together twelve 30 degree triangles to create a complete circle; six to create a half-circle; or three to create a quarter-circle. Or, use the angles to create a variety of intricate 12-inch finished blocks - no paper templates required. Creative Grids quilt rulers are made with exceptional quality. Easy-to-read black and white circled markings allow for great accuracy and easy viewing on both light and dark fabric. One-inch grid with 1/4 inch increments. Embedded Gripper Dots and Strips hold fabric while cutting. They are easy to use, and cutting is abreeze thanks to the non-slip grips on the back. Press down lightly on the ruler, and the non-slip circles grip the fabric. Yet, when you are not pressing down the ruler, it will slide easily over the fabric.
