I like the velcro cables ties that stay attached to the cable, like [1]. Wrap the cable in a loop, then secure the loop with the velcro. Larger cables get two ties on opposing sides. Do not squish the cable because it will get all kinked; just keep it in a loop, and stack all your wrapped cables as a cylinder.

The diameter of the circle depends on the cable length and thickness. 2m USB cable should be 10cm, 3m power cord should be 20cm, and 10m Ethernet cable should be 30cm.
