Pattern: Heartbreakingly Cute Pilot Cap, from Mason-Dixon Knitting Outside the Lines
Yarn: Oasis Yarn Aussi Sock, in "Faded Valentine"
I found it really difficult to get gauge using sock yarn, but decided to just go with it. The resulting fabric is stretchy enough to fit a baby's head (as demonstrated by my new model, who not only has eyelashes but doesn't cry when we play "dress up".)
This is the same yarn as I used on one of the BSJs, so now N has a complete ensemble in Faded Valentine. If only the socks would stay on.
