My friend Lynette made herself this lovely shawl on her peg loom.
She is now making peg looms for sale. They are generally custom made, to your specifications regarding peg width, distance between pegs, and how many pegs.
Painted, or not painted.
If you're interested, just drop her a line at daisyhillhandiworks at hotmail dot com. She has limited internet access, so your best bet is to send her your telephone number so you can discuss the specifics of what you want.
