The OLFA QR-1x12 frosted acrylic ruler is a slim tool for accurate measuring and cutting in quilting, sewing, and paper projects at the workstation or in a travel kit. Its 1 1/4 in × 12 1/2 in (32 × 318 mm) shape suits seam allowances, narrow strips, and marking straight lines, with a printed grid for quick reference. The frosted finish improves contrast so the black markings remain easy to read while you align edges.
