In case you didn't know, there's a version of the classic zip tie that has a mounting hole head so you can screw or nail it to a wall. Great for holding up bundles of cables/wires, lengths of light tubing, Christmas lights, rope lights, or whatever else you can dream up. They say they're rated for 50lbs, although I haven't tested that for myself.

As Donald Bell puts it in this Cool Tools video, “if you can zip tie it, you can hang it on a wall.”

They come in packs of 100 ($7), 200 ($10), and 500 ($23), all of which also come in “clear.”
