Looking to buy a leather sewing machine, need help. I been looking at juki 1541, cobra 18 ,sailrite 111 and used juki 563. i would like to be able to do leather from 3oz. to 13oz. harness leather with 207 or 277 thread. It would be anything from bags, upholstrey to some tack (breast plates and head stalls). Any idea what machine would be the better option? maybe not even one of the ones I been looking at???I like to have reverse and a flat bed. Hopefully somebody can clear my head a little.
