Creative Grids Quick Trim Ruler 3.5x12.5 Rectangle
By using the holes drilled in the center of the ruler, drawcircles from 2" to 22" in diameter- and every half-inch inbetween. Use the 45 degree angle lines- that cross at 1/4"to trim points from half-square triangles and flying geese.Embedded Gripper Strips hold fabric while cutting.
