"What Rotary Cutter do I use" is one of the most often asked Questions.
I have three Olfa cutters but the Daisy edition is the best!! I bought my first one at our local shop Quilters Haven and then I was so happy with it I ordered another one on Amazon. (I've learned over the years if you really like something you better get two or three.)
I'm not sure if they're still available but if you can I'd highly recommend it.
