Oh, shudder. I'm so sorry you and the other posters have been injured. I am an accident-prone, sort of clumsy person who is not good with small-motor activity and I am sure both those accidents are waiting for me. My husband worries whenever I use the rotary cutter...but my own biggest worry is that I will use the cursed foot pedal and put my foot on it too soon while I still have fingers under the needle. I much prefer the start-stop button for safety reasons.
You are all so brave!
Wish you a quick recovery!
