I pretty much followed the instructions for the second size (baby), except that I knitted until the hat measured 7.25 inches instead of 6 inches. It looked better proportioned for the circumference of the hat, and I thought he would be able to wear it longer. I made three 1-5/8” size pom-poms with my Clover Pom-Pom maker. Lucy shows how to make them here:

This is a very cute little jester style hat. Even though the yarn is very fine, I think I’ll do a provisional cast-on next time to make the hemmed headband even flatter.
