This is the Stella Pixie Hat in two variations. One for the new baby in size 3-12 months. Oh, by the way we are naming him Desmond Nicholas.
Josie was not so excited about modeling it. I suppose she knew it was in boy colors.
Isabel got one too. Same pattern, except I used worsted weight yarn instead of sock yarn. I followed the 12-24 months instructions.
All details are found on my Ravelry page.
