One suggestion I have is to look at cheap plastic coathangers. These are
about 1/4 inch in diameter and are not vinyl coated wire hangers. Several
insulators can be cut from a single coathanger. Since you can often buy
these hangers for around $1.00 for ten, a few dollars could provide a good
number of insulators. If you don't like the color, spray paint them with
Krylon or another acrylic paint. White will provide the best ultraviolet
resistance. I would limit my wire size to 16 Gauge or smaller as this
plastic is quite brittle.

Excellent, comprehensive, broad in scope, generally-good-advise, etc.
