This one size fits most hat fits well and stays put while you play outside!
The bun hole in the top can be left open for a looser fit, or crochet in a hair tie to tighten it up.
The hat is worked in rows, joined after last row, and then turned to work the crown.
-The finished measurement before joining the seams is only 15”, but the hat stretches to fit up to 22” because of the ribbing.
