I'm starting to feel the itch for a sewing machine to help with some of the lighter work lilke wallets, belts, maybe a small bag or two. I've come across a bunch of vintage Singer machines locally, and I'm wondering… are any of the old singers actually suitable for leatherworking? I know they're built like tanks, but can they really handle leather without burning out the motor or skipping stitches? If you've had success (or failures) using a classic Singer on leather, I'd love to hear your experiences
