I made one this winter. i made it larger than shown because i was carrying almost all my gear in it.(9x9 tarp,boiler,stakes,pan,etc.) I wanted to carry all my gear to a camp site and i found it was easier to use than rolling my gear in the tarp and slinging it. i used canvas and leather as suggested. Because of the angle of the top strapes when carried you need that leather top hinge piece and a solid stitch job or it could pull out or tear. Make the front flap straps long enough and you can carry a coat or spare clotes in between.
