Designed for garment sewists, cosplayers, and avid quilters, our game-changing Sew Magnetic cutting mat is now available in a larger version 24in x 42in (it fits a full yard - or meter! - of fabric)! A non-slip, adaptive way to cut – for use with the Sew Magnetic™ Ruler of your choice (sold separately, or purchase a complete system set!). The Sew Magnetic Cutting mat is a double-sided, 7-layer self-healing magnetic cutting mat – one side is dark grey with white lines, while the other is light grey with black lines. Choose the side you feel will help you see things the best, depending upon the color of your material – or, just for what'll look Insta-ready when you go to share your projects on social media. There are 1/2" numbers and lines for those quilters who cut most of their pieces on the 1/2in, and of course, there are standard whole 1" numbers for all the other sewists and crafters who cut this way – and yes, there are 1/8" and 1/4" markings throughout the mat, and we've added 30 degree, 45 degree, and 60 degree guides as well. Are You a Leftie? We’ve designed a true left-handed cutting mat just for you – with the numbers mirrored from the right-handed version so that you can cut the correct way for you!
