Like Bruce, I just take a coil of paracord and don't bother with anything fancy. 20' is in my backpack, a 100' coil is in my truck. After a short time the knots/twists/turns in the cord become something you need to deal with when you use it for something other than as a fashion accessory. I cut it to length, melt the ends, loop it and call it done. YMMV
