When I played with Flying Pieman, we had access to the sort of reusable cable ties shown in Richard's link above; we used them for power leads, mic leads, speaker leads and even had some kept for the octopus cable. I still have a few left and guard them, as I've not seen any electronics shop in the last decade or so that even knows of their existence.

While I acknowledge that Joe Offer's technique works for ropes (up to about 10m) if you can hang the resultant coil I prefer the climber's method of coiling with an imitation whipping to keep the coil intact; I've had trailer and roofrack tiedowns kept intact like this for years without the ropes becoming difficult to deploy.

Some types of cable insulation make proper coiling difficult; hypalon seems infinitely flexible and is often used for scientific instrument cables. The copper in the internal conductor can work harden if coiling is not carefully done and knots of any sort (even Joe's relatively gentle version) should be avoided like the plague. Wrapping coils around your upper arm is deadly to the conductors and is a real no-no, as it continually imparts a twist that is never reversed.

Coiling so that every alternative loop is reversed in its direction ensures that a cast or walk to lay the cable out leaves it flat with no residual twist. You have to ensure you haven't inserted an end through the coil though, or you'll find an overhand knot for each pair of loops in the coil's length; this is basis for the sailor winning the knot-tying competition with the tailor for the maiden's hand so celebrated in folksong.

It can by a trying time when learning the technique but I use it for all leads, cables and ropes (even garden hoses), no matter how I secure the resultant coil, and I've taught novices in about 10 minutes.

But I also inherited a length of plywood shelf a couple of feet long and three inches deep; it had thin slots (3/16"?) cut into it every inch or so; when mounted high enough in the wardrobe it's perfect for hanging all those RCA leads and even the more recent computer cables and USB leads.
