The 90° Double-Strip ruler designed by Rachel Cross for Creative Grids® gives you the ability to cut two different shapes all with the same tool. · Made in the USA with high quality acrylic and precision measurements ensuring accuracy for your quilting, sewing, patchwork, and crafting projects. · Creative Grids® exclusive non-slip grip allows you to easily slide the trim tool over the fabric until positioned correctly. Then, when slight pressure is applied, the grip holds the trim tool in place, eliminating slipping while you cut. · Easy to read black and white markings. · Use the straight side of this double-strip ruler to cut 2-1/2in strips. Sew two of those strips together to create a 4-1/2in wide strip set. · Use the other side of the double-strip ruler to cut three 90° triangles at once that will finish to 4in. · Multiple layers can be cut at one time. · The key holes in the ruler enable the rotary cutter to cut the angled sides without damaging the ruler. · Comes with fully illustrated step-by-step instructions. · Scan the QR code printed on the ruler to view a video demonstration and to see patterns that use this ruler.
