I just got back from sourcing... what fun, going to stores, rooting through back rooms and sifting through piles and stacks of things looking for treasures :)  Scanning the scrap metal yard I found an old busted-up microscope!  I wonder what bits & bobs are held inside?  Gears would be a neat find, or any interesting metal things, I suppose.  They could be made into pendants or pieces of wind-chimes maybe... I also got a couple of giant cardboard carpet spools/tubes.  I've got some interesting ideas brewing for those, but they aren't quite formulated enough to share, yet.
