One of the most utilized tools in the quilters workspace aside from the rotary cutter is the cutting mat.
A quality cutting mat will not only provide a sturdy cutting surface but also self-heal in the process. The composition of the mat should not dull your rotary blade.
Although mats come in a variety of sizes, a new quilter will want to purchase an 18″x 24″ mat to get them started. This size is easily portable for classes and retreats.
