I have almost done this on several occasions but stopped just in time. Whew!! Thank goodness I caught myself. I can't offer any solutions but I feel your pain! :x

I now have 2 cut and press. one I use for press only and one I use for cutting only. Love Idiot #2

ohooooo nooooooo , try to sew the tear and maybe sew a cover to the complete circumference. or a removable cover....maybe two of them lol

I'm so afraid of doing the same thing that I don't let my rotary cutter stay in the same room!
