The multi-sized 2 Peaks in 1 Triangle Ruler designed by Rachel Cross for Creative Grids® combines the angles you need to create triangle-in-a-square blocks which require a two to one ratio. · 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 ruler over the fabric until positioned correctly. Then, when slight pressure is applied, the grip holds the ruler in place, eliminating slipping while you cut. · Easy to read black and white markings. · 1/4in dashed lines around the perimeter of both triangles to highlight seam allowances. · The unique keyhole cutout allows you to rotary cut both triangles with one tool. · Size of strips needed and their finished sizes are included on the ruler. · Comes with fully illustrated step by step instructions. · Scan the QR Code printed right on the ruler to view a how-to video and to see the patterns that can be made with this ruler.
