I do get some contrast from just mixing different steels. Black, dark grey, grey and light grey. I just love the way nikkel pops, if you know what I mean.
I don't have access to bandsaw blades, I usually cut up hand saws, as people often give them away when they are dull. I do know of a saw mill or two in my area, maybe the wouldn't mind me diving for a few of their used blades.
Thanks for the auto store idea with shim stock, I might ask around if I can dumpster dive there for them. I kind of need all of my money for food....
