Hello! I have a sling bag that I really like, but the strap doesn’t take it as close to my body as I would like. I have a sewing machine, but I have never used it for stitching seatbelt webbing. What sort of needle would I need to use, and which type of thread would be best suited for the material?
Likely not much, really. Try going slowly at first, and speed up if it goes well.
