The Omnigrid 6" x 24" ruler is the standard, all-purpose ruler for cutting every shape when quilting - strips, borders and bias pieces; it can also be used to cut across joined strips and to cut geometric pieces for patchwork; its generous length covers the width of fabric. Cut strips and trim fabric edges during quilt making or when executing a variety of sewing and fabric craft projects with this ruler. It is made of heavy-duty durable acrylic material for use with a rotary cutter or a straight-edge blade. It has multiple degree angle lines for easy pivot of 30, 45 and 60 degree cuts. The laser cut edges allow for smooth, deep cutting and edge markings for accurate measuring. The patented double-sight lines show up on light and dark fabrics. It features a left- and right-hand numbering and angle system.Details:6" x 24"Laser cut edgesDouble-sight linesAcrylic
