I just finished making this hat for my daughter. The last sun hat ended up in our neighbor’s mower – don’t ask! I used a Simplicity pattern (don’t remember the number). I made the 18 month size but it was still a bit big. She loves it. I brought it in after her nap and she pointed to her head and said “Hat! Hat! HAAAAT!” I used a home dec fabric for the outside and the inner facing is a lightweight cotton. I didn’t have to buy anything to make it, so that was a plus. I am not too happy with the way it turned out. It’s kinda crookedy. But everything looks good on babies.
