I am pretty sure that I won't wreck my 99K in a cabinet if I try to repair my dogs halter with it but I need some reassurance. I have to sew through an intesection consisting of several layers and I am concerned that I could throw the whole machine out of whack. Don't want to use my computerized machine so thought this would be a good alternative. Probably need to use specific needles and thread also? Thanks for any feedback or suggestions.
before i'd risk i t, I'd take it to a shoe repair shop.
