I would recommend a good serger for anyone that sews clothing of any kind as well as your bags. Sergers are a great invention. The first one I ever saw was about 27 years ago and I bought one on the spot and took it home and used it right then and there. Was one of the greatest finds I ever had. If need be take lessons so you can get full benefit from using yours. Doesn't have to be fancy to be worth having, just a good one.
