I was watching Dan Wowak Hacks on the Coalcracker channel which are full of ideas and since I had timber to spare thought Id try to drill a toggle without a drill and turn it into a ratchet strap for a bedroll. I believe I first saw the tensioner system on Felix Immlers channel so I also put a link to his site. Lots of cool ideas on there as well.
