The Creative Grids Stripology XL Ruler is large enough to cut an entire fat quarter or half yard of fabric without moving the ruler! Decrease your cutting time even more by cutting multiple layers of fabric at one time. The slots every 1?2 inch have a tear drop to aid in placement of the rotary cutter and ensure accuracy of every strip. 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, with cutting slots every 1/2in. Whole inch, half inch and quarter inch increments are marked. Additional markings for 1/4in and 3/4in cuts are also included. For quick reference, 1-1/2in cuts are highlighted with black stars and 2-1/2in cuts with black squares. Use the black lines to square up blocks in whole inches up to 12in, and the white lines to square up blocks in half inches up to 12-1/2in. Use the 45 and 60 degree angles to cut perfect diamonds and triangles. Great for fussy cutting and trimming embroidered blocks. The flexibility of the ruler allows it to adjust for the thickness of the embroidery, giving you an accurate trim every time. Comes with fully illustrated step by step instructions.
