The hats are from Itty Bitty Hats. Fun to do. A little fiddly with the pieces to knit and stitch on. Rather like doing a stuffed toy. But they're cute once on. I wouldn't knit them as long as the pattern called for, at least for two or three year olds. The pattern says 4.75 inches for the white part and I think 4.5 inches would be enough. They're out of Knitpicks Swish and this is the first project out of that yarn that I've liked. It was in my stash and it was, after all, hats that last for a season so why buy something expensive? I hand washed them and then threw them in the dryer which worked well. The pictures here are after they've been worn and hand washed and laid out to dry. I think the dryer shrinks them back up well.
