Even better (IMO) is strands from stranded wire. The stuff that is called out as "7x30" (22 AWG) is seven strands of 30AWG. Already tinned, it can be very easy to work with. And stripping the insulation from a seven-strand piece of 22AWG is easier (again, IMO) than trying to get the Kynar off of wire-wrap wire.
