Measuring 6 1/2″ x 6 1/2″ x 1/8″, our Square Up ruler is ideal for trimming small blocks and pieces. The clear, easy-to-read numbers (including nicely marked half and quarter-inches) and precise lines are digitally printed in white and black for good legibility on all fabrics. We are proud of the “just right” non-slip backing that provides a firm, safe grip when cutting, yet glides smoothly on fabric when you’re lining it up. Many rulers are either too “sticky” or have insufficient grip. We think this one gets it just right. The 30 °, 45 ° and 60 ° markings make cutting accurate triangles easier.
