I'm looking to sew up some leather collars 2", leashes and harnesses on a regular basis. I am very good at figuring things out (I think) and would like a machine that can handle this with ease. I have never sewn anything before but am pretty good with my hands. I'm looking to use 8-12 oz material for this. I also was wondering if a machine that can handle this could also handle sewing material like nylon, jute, and French linen? Any advice, info, or if you know of a used machine for sale that has these capabilities your help would be much appreciated!
