I used two lace yarns, one 2ply alpaca of unknown origin and a leftover of silky mohair by Martin’s Lab. The whole hat weighs about 26 g. It is very soft and light texture, but hugs your head and keeps in nice and warm.

I couldn’t get the gauge with this yarn, so I sized down to a childs size to get a correct size for an adult. The hat is quite drapey and slouchy.
