Martelli Templates & Fussy Cuts are made to make your cutting easier and more accurate. The no-slip material creates a vacuum seal and locks up to 32 layers of fabric in place. Most people feel comfortable cutting 8-12 layers without sacrificing the accuracy. If you don’t cut straight, you’re never going to sew straight and you won’t have a perfect quilt. Because the material locks your fabric in place, you just need to lay the template on your fabric and turn to make your cuts. No more measure-cut, measure-cut, measure-cut, etc. The templates, like their rulers, are cut on a laser machine, so they were made with 100% accuracy. They can help you cut out enough blocks for a king-size quilt in a matter of minutes. Template features Martelli no slip material
