This hat pattern is the easiest of all of my recent patterns. There are no fancy techniques in it. It all knits in-the-round, from top down. The only thing you’re supposed to be familiar with is decreases & increases and basic short rows.
Why this title? Because it resembles me the slowest brain waves - delta waves, which our brain produces in a deep, dreamless sleep. I can’t promise that you will be able to knit this hat while you sleep, but your brain won’t get overheated with this pattern.
