In January, I was cutting fabric and my rotary cutter hit a nick in my ruler (that I did not know was there) and it jumped up and hit my hand. I ended up having to get 5 stitches and that same day I went and bought a klutz glove. I don't always use it for mine is a little too big and it hard to work with. But I'm glad I have it. You never think you'll need it until you really cut yourself. It helped me not be afraid of my rotary cutter anymore when I was ready to get back to work.
