“Newbie” because it’s a great first hat for new babies and new knitters (but fun to make in a couple of hours for more experienced knitters needing a last-minute gift).

You can use any combination soft, fingering-weight yarn/needles that will yield approximately this gauge: 10 st x 10 rows = 2” or 5 cm sq.

I also made an adult-size hat using bulky yarn and large needles.
