Fussy cut and easily trim small pieces using the Sew Magnetic™ 11" Rotating Self-Healing Cutting Mat – plus 6 SewTites® Boosters! Use the Boosters to secure your fabric, paper pattern pieces, and acrylic templates as you cut and rotate your project. Use the mat with the Sew Magnetic Ruler of your choice to easily cut and trim small projects and quilt blocks (sold separately). 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 1" numbers and clear 1/8", 1/4", and 1/2" grid lines as well as 30°, 45°, and 60° angle lines for easy and accurate measurements.
