A friend of mine has recently had a baby so over the past few months I've been making this. Had to do a final rush to finish it and get it off as soon as possible as he's a bouncing 10lb 2 oz (4.610kg) and he'll be grown out of it before long! LOL
and here's close up for all you knitters.
It's an interesting pattern. You start off with one square that's decreased on the diagonal and build up from there. I'm doing myself a waistcoat in the same pattern with a random cotton yarn. It might look really naff on me when it's done but the completed version at the Hobbycraft show looked fab.
