All hats have to be in by 1 December, and there are more advanced otions on the Innocent site.
I did this last year, and sent off 30 mini-hats, but I only started in October. Last year I did it without buying any wool, just using leftovers. This year I’ve had to buy some wool, as I don’t like making the pompoms I’ve been adding felt flowers.
This year’s target is 100.
