Here it is, the fifth Aviatrix I've made. I love how quickly these hats knit up, and on two needles. (Um, by the way, Gemma doesn't really have a lumpy head, just hair done up into a little top-knot!)
Justine Turner has actually improved her original pattern, creating options for sizes newborn to 4+ and instructions for using sportweight, DK or worsted weight yarns.
I knit this one from Knit Picks' Andean Silk, in Cranberry. It is very soft, and cozy. It fits her rather large head just right now, which means it will likely be outgrown before winter is through.
Which gives me an excuse to go ahead and knit another one...
