1. Buy Rugged Tote Pattern
2. Follow instructions
3. When you get to the straps, I cut a length of 1" Nylon Webbing that reached from the outside strap marking, to the bottom of the inside pocket, with a little extra room for a D ring at the top. I threaded the D ring on, and lined them up and pinned them in place so that I would stitch through the outside strap and inside strap at the same time. Repeat for each strap.
