Omnigrid 8" Right Triangle Ruler, Half-Square Triangle Quilter's Ruler

The Omnigrid 8" half square triangle ruler is used to create half-square triangles for finished quilt blocks up to 8". It has seam allowance calculations included in the measurements and is easy to manipulate for smaller triangles when quilting. The patented double-sight lines show up on both light and dark fabrics and the laser cut edges help create a smooth, deep cut. It is best used with a rotary cutter or straight-edge blade.
