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. Use the vertical lines to fussy cut stripes and to cut half-triangles. 1/4in seam allowance is clearly marked down the middle of the ruler. Use the 30, 45, and 60 angled lines for endless design possibilities. Comes with fully illustrated step by step instructions.
