The knitted hat seems to be the current favourite project - a good way to try out a new stranded pattern, but quick to knit and using modest amounts of yarn. Here are two more recent ones -
They are called Choc button hats, because the pattern reminds me of chocolate buttons, and the purple/brownish coloured yarn reminds me of Cadbury's chocolate wrappers.
The black one has a slightly higher crown, as I absent-mindedly decreased in a different way from the intended one. So now it would suit a wearer with bigger hair.
