With a scalloped edge and non-slip base, the Omnigrid 360 Rotating Cutting Mat makes rotary cutting much easier, even in a small space. Easily rotated with the tip of a fingertip, the 14” mat features 1/2” overall grid lines for easy alignment, along with centering measurements and 30-, 45- and 60-degree markings for angle cuts. Rotating your work instead of your body not only improves accuracy, it saves time and reduces fatigue. Use it for paper piecing, fussy cutting, half-square triangles, miniature work and more.
