We got a knitting machine out - a Brother KX350 Mid Gauge machine and did some hand tooling. (No photos of it in action as the demonstrator is also the photograpaher!) There were a number of different cables and twists shown, plus a few other techniques.

We also had the usual show and tell. Christine was wearing a very intersting shrug. Luckily there was a whiteboard and pen available so a few sketches and notes helped with the explanation of how it was knitted.
