The thinking is that despite having a wife who crochets and a daughter who knits, the old man doesn't have nearly enough embarrassing knitwear.
(That's me modelling it)
More seriously, I thought it would be a great use for the All Seasons Chunky which was a prize from Knit Now magazine. (I bought a fourth ball - though if I'd made it a more sensible length, three would have been plenty...)
The pattern is A's Manly Scarf by Johanna K Sarten - a lovely stitch pattern and knit lengthways.
