Y'all, on a whim, I bought this funny-looking rotary cutter from Martelli Notions. I LOVE IT! I sliced and sliced until that strip of fabric was confetti fibers; and my hand wasn't cramping nor fatigued when finished. It only took a couple of minutes for me to get the hang of it, too. I'm notot affiliated in any way with Martelli. One of their videos popped up after watching MSQC's weekly youtube tutorial. Like I said, I bought it on a whim b/c they are on sale. I bought the left-hand version. I'm getting ready to go back and purchase the right-hand version for DH. I really think it will be a useful tool for him as well. Anyhoo, just wanted to share in case you suffer from cramped rotary hand, too. I'm really excited about this new-to-me product. Happy Quilting!
