RG-174 Coax Cable & Heat Shrink.

RG-174 SHIELDED COAX CABLE

Very nice quality. Used as input wiring to avoid oscillation and other potential noise problems in amplifiers.
Use center wiring as normal hook-up and the outer shielding is grounded at one end of your run.
At the other end you trim the shielding back. No connection.
Usually 2 feet of this will cover the average build.

... $0.50 per ft.

HEAT SHRINK TUBING 
1/8" thick polyolefin Heat Shrink. Shrinks down 50% in size.

This size works for 18-22awg hook-up wire. Has a rubbery feel and is very flexible and easy to work with.
Some heat shrink feels like plastic and almost cracks when you bend it. 

... $0.75 per ft.
