Winter is suddenly COLD. My reaction is to knit things that are warm and soft and bright:
I made this from Ysolda's absurdly pretty Rose Red pattern and Diamond Yarn Angorissima, which is pure angora, and it is so soft and it is bright red. It became my favourite hat as soon as I blocked it; it's big and warm and barely weighs anything (35g total, which is around a ball and a half of the yarn). I knitted the largest size of the pattern with a small modification, which was switching from 4mm to 3.5mm needles for the cabled band around the bottom; angora doesn't really have any memory and the ribbing tends to stretch out without springing back. This way it is tight enough that it doesn't slide right off, but the rest of the hat can still slouch.
I like to make a little loop in the centre of a beret instead of a stem, which maybe makes this into an even sillier hat?
