Loose cord has a talent for turning into a knot just when you need it. Whether it is a spare guyline or a length of utility cord for camp organisation, a simple figure-eight wrap keeps it easier to handle.
Hold one end between your thumb and palm. Wind the cord in a figure-eight around your thumb and little finger, leaving a short tail. Slide the loops off together, wrap the tail around the middle a few times, then tuck it through to hold the bundle.
Keep different lengths separate rather than tying them into one giant bundle. When you need a length, undo the tail and feed the cord out without throwing the whole lot on the ground.
Check for fraying as you pack away, and keep general-purpose cord separate from any specialist equipment.
Field tip: Pack cord ready to use, not ready to untangle.
