A collection of links for places to buy the ingredients/tools for your project and patterns for your projects. I'll add more as I find them.
Tools/Ingredients:
http://www.theringlord.com/ - one of the best places to go for rings, lots of choices and good service.
Patterns:
http://artofchainmail.com/patterns/ - good place to start for various armor patterns, plenty of good pictures and close ups so you know how the rings are supposed to interlock and lay.
