Tried running the tracing paper through the copier at work - didn't work for me. But we do have a paper cutter here so I can cut it down to the right size to fit through the machine at home.
This will give me an excuse to check out some craft/art supply stores while in the Twin Cities. I have ordered from Dick Blick before, they have all kinds of neat stuff!
I think I'd like to try making smaller blocks too.
