Leather is 6-9 oz. Thread is the waxed nylon that Tandy sells for hand-stitching, not sure of the size. Sometimes my bags are 3 layers thick in places, so thickness could approach 3/8"

I am thinking of getting a Techsew 2700, 0r 2800. I attached pics of a couple of bags that I have made(hand sewn). My question is, will these machines do this sewing?

Yes. I did build the car, but it is not a kit.

Yes, lots of hand sewing. Looking and saving for a machine.

Pics of my latest bag. Started experimenting with leatherwork about 6 months ago.
