Well, I can't afford a trip to Tucson any time soon, but just learning that there is such a thing as steel wire to work with piqued my interest. That might be an interesting addition to what I make.
Ha. Good luck FINDING steel wire to buy. So far, that project has been a bit of a bust. Even the sites that list it in their catalog are flagging it as being out of stock. I'll have to keep looking. Maybe the holiday rush obliterated the stock of a lot of sites.
