Make a v-notched rope carrier out of plywood or a 2x6

drill a hole in the lid of a mayo jar and put the cord in the jar and feed the rope thru the top of the jar it makes it compact and easy to pull out and put away

Make about a 8-12 inch loops and when you get enough wrap it around itself and pull it back through the eye on one end, then slide up the wrap.

field and stream has an article that I seen in a recent issue on how to make a gun sling out of parachute cord
