My chinese patcher in Leather Sewing Machines Posted March 12, 2018 · Report reply I am digging my patcher as well. It took me a while to get it timed perfectly and work out the kinks (knowing nothing about sewing machines) but when I did, it was magic. I spent an hour yesterday replacing a zipper on one of my daughter's Cordura tote bags with a heavy duty replacement. Not super beautiful, but functional, and black on black kept my mistakes from showing too bad. I have gotten some heavier thread to work with the needles that come with it, just 15 weight upholstery thread for now. Haven't tried larger. I made a little bag out of scraps to hold my common sewing tools, and did some stitch drawing practice to learn how to control the thing a little better. I bought a manual off of a guy named Darren here that helped me a ton! It's a good little machine that can punch through significant weight for the price.
