Omnigrid's Folding Travel Ruler offers full-size functionality in a convenient folding design. Fully extended, the folding travel ruler is long enough to cut bolted fabric or trim finished quilt tops. You can also use the longer length with home decor projects and wider fabric such as quilt backing. There are multiple degree markings along the ruler for bias cutting. Omnigrid's rulers have laser-cut edges and are made of heavy-duty acrylic that will last for years to come. This foldable ruler has patented double-sight lines that show up on light and dark fabrics, as well as a right and left-hand numbering and angle system.
