The rotary auto blade is designed to cut fabric without backing such as an iron on applique sheet. The rotary auto blade makes it possible to cut delicate and stretch fabrics by minimizing the fraying of fabric edges. The characteristics of the rotary auto blade make it suitable for cutting large patterns with few sharp angles. Use the included activation card to activate this kit in CanvasWorkspace Web and download a recipe book and 63 patterns that allow you to create a variety of projects using different types of fabric. The downloaded patterns can be imported into the machine and edited. This kit is compatible only with the Brother ScanNCut DX cutting machine
