I used a pattern from a Romania leather guy off of YouTube. I think he's probably pretty well known. My hands hurt afterward, but I learned a lot and am excited to start my next project. I want to make large leather goods like this...maybe a duffle bag, hand bags, or a backpack next. I don't want to be a seller of my projects. I hope to become good enough where I can gift these items. I included a link to two pictures of my tool bag.
