Hi everyone. Awhile ago I purchased a leather Bridger bag kit. I finally have some time to tackle it. It comes with #16 thread for stitching. The instructions are little lacking in thoroughness. Do I use a single strand of thread or double strand? Single to me just doesn't look like enough thread? Should I wax it? Also what length of thread should I work with. I have hand sewn clothing before and I know the optimum lengths to use to avoid knots, twists, etc. Is there such a convenient length when stitching leather? I'm sure to have more questions as time goes on but this is it for know. Thanks, Kurt.
