I’m sorry about the misplaced insulation paper. All it is, is thick cardstock paper (that won’t get punctured easily), so you can just use that. It wouldn’t hurt to cover it with a layer of electrical tape for extra puncture protection.
There is nothing special about the wire. You can use whatever insulated wire you have that will fit into the pcb holes. Don’t use thick wire that is hard to bend or barely fits into the pcb holes. Whatever wire you are using is probably fine as long as it fits that criteria.
Good luck!
