Fussy cut and easily trim small pieces using the Sew Magnetic 11"" Rotating Self-Healing Cutting Mat. Use it with SewTites Boosters and the Sew Magnetic™ Ruler of your choice to secure your fabric and templates or pattern pieces while you cut and rotate your project. No more re-aligning after each rotation – or rotating your project instead of the mat. It rotates smoothly and easily with the touch of a finger, and the non-slip back keeps the mat safely in place while cutting. Perfect for sewing and crafting in small spaces and while traveling. Includes a grid with whole 1in numbers and clear 1/8in, 1/4in, and 1/2in grid lines as well as 30-, 45-, and 60-degree angle lines for easy and accurate measurements.* Made of: Plastic & Magnets * Use: Cutting System * Size: 11in
