4 needle knitting

Anniemay's knitting a jumper with no seams.  It starts at the neck and then by some mystical process, progresses outwards down the sleeves, finishing at the bottom of the body.

This means nothing to me, but I understand others will get it.  All I know is that it's very technical and starts with some swearing if you haven't done it before.  It also requires absolute silence, so I have to type this very very quietly.
