Super easy, Super fast.
I couldn’t find an easy pattern I liked, so I made my own.
The left pic is the first try, right pic is the finished pattern.
Fits average head, comfortably.
Fits larger head snugly, depending how the wearer likes.
Usually get 2-3 hats per skein, or 5 per if using 2 colors.
Time: 2-3 hour max for a novice knitter.

from my hands to yours, enjoy!
