Hi mross - I like your clothes pin idea. I wonder if you might benefit by incorporating some rubber bands so as to make a double headed spacer. Use a rubber band or two to hold the overlapping "legs" of two clothes pins together. This would provide grips at opposite ends.
Personally, I keep my mono block power cords off the floor using 3" solid hardwood blocks (birch, I think) from an on-line craft supplies seller. I manage to keep my speaker cables separated and off the floor just running them across the top of the furniture I use for an audio cabinet. The other interconnects and power cords behind the rack are separated and kept off the floor as much as space, length and gravity will allow. I do use some cut up rubber flip flop soles to keep ICs off power cords where those cross. Elsewhere that crossing and contact of wires must occur, I try to make it happen at right angles (or as close to 90 as possible). I must not be a true audiophile because I don't get too obsessive about "dressing" my wire.
