For FYI purposes only...
Wyr Knittr, a machine allowing you to knit with wire, is getting poor reviews across the board, by folks purchasing this product and even experienced jewelry makers.
As an alternative, you can knit with wire without a machine. There are wooden tools with pegs available, OR you can just use your regular knitting needles and very fine gauge wire. A couple of books are on the market about wire knitting, available at those big online book retailers.
