If you know an auto mechanic, they are apt to have a chunk of brass shim stock in their tool box. If all else fails, walk into any machine shop and ask, they are sure to cut you off a chunk. The chunk I have is about 3" (I think that might be 75 some kind of meters for you metric nuts) that I peel paper thin layers off of to make lenses as needed. I must have made a couple dozen lenses off that little square and can't imagine ever using it all...well, maybe if I got one of those WPPD hats and made it into a multiple lensed camera by utilizing the air holes...yeah, I could line the inside of the hat with a black garbage bag...wait...I think that's another thread...
Man, oh, man, some of those pictures people are posting are fabulous. You get a load of that one "I Love My Husband"? I think it's on page 24 maybe? Beautiful. Jim Roy, Washington
