For Christmas I asked for a bunch of sewing things including a rotary cutter. I received a Fiskars Rotary Cutter and got started using it. The first couple cuts were fine, but after a few uses, I started having to press harder and harder to cut through the fabric. Even then, the blade often skipped across the fabric, leaving it joined in a few places across the cut. With a sore hand and crappily cut fabric I gave up on using the rotary cutter. I purchased a pair of inexpensive scissors at the fabric store and vowed to use them only for fabric.
My fabric store has a club membership that you pay $15 a year to be part of. That gives you discounts all the time (on almost everything) of 25-35 % and allows you to shop on their member days every couple of months (when everything is 50% off).
The cutter easily cuts through 4 layers of quilting cotton or several layers of towel without any skipping. I do not have to press down hard for a proper cut and I find this cutting easier to control than the Fiskars. I can quickly cut, without a sore hand! I am incredibly happy with this rotary cutter!
