If anyone wants info, tips, etc. on commercial sewing machines, I might be able to help. I currently have a Nakajima Rex sewing machine, btw. Big and sturdy, it will sew anything you can fit under the presser foot. That includes fingers. Don't ask how I know. My tigress has a '50's vintage Brother home machine that runs better than most new machines. $27 USD from a goodwill place. Kel
