A very fast knit.
This super chunky yarn is very soft and warm. I used size 20mm needles but that’s not available as an option in the Ravelry dropdown.
For the small size I used 1 kilogram of yarn and hardly had any left over so I made the pattern instructions to knit the sleeves from top down and the sleeve length could be adjusted to be three-quarter length in case someone is running out of yarn. The buttons are 5cm in diameter (ordered off Amazon), they are thin plastic buttons so not at all heavy and I reinforced them with thinner yarn to hold them better in place.
