I have good intentions at least of making my own - I'll start a thread when I figure it out.
So what shall we say - get stuff from the dollar store or other discount stores, Wal-mart or the like...how about grocery stores? Craft stores I might disallow, and a specialized hardware store like Home Depot makes it just too easy.
And the only "specialty gamer supplies" allowed are superglue, plasticard, and as little putty as possible?
