Several times we discussed on this blog about the importance of the number of the needles of the machine producing socks, in order to have the best knitting.
Sometime a picture is worth hundreds words, so...
|216 needles machine|
Actually looking at the picture the machine looks like a "black hole" where all is disappearing, while it is really the reverse, it is the hole where something is appearing..
The one in the picture is a mono-cylinder machine. It means there is only a line (cylinder actually) of needles; we produce here our "embroidered" socks.
