This is the hat I knit for my daughter. She is too hip for her own good at six years old! I used Lion Microspun and did the seaming on the inside for this one because she wanted it to "poof" up a bit. It fits her perfectly because the DK weight yarn made up the size difference. I was guessing when I substituted that it might work and THANK GOODNESS, it did. Her awful, digusting Brat makeup head is modeling it because she wouldn't do it for me.
