Here is a super duper easy hat pattern that is simply adorable! For the record: I'm sure someone, somewhere has a hat very similar to this as it is SO basic, but since I made it from the lightbulbs in my own brain I'm posting it here. Enjoy! And please let me know if you see a mistake.
1 skein super chunky yarn
#8 circular needle
#8 double pointed needles.
Cast on 66 stitches with the circular needle.Join in round and work in 1x1 ribbing for 1 inch (or desired length for brim)
**Knit 5 rows,
Purl next row**

repeat ** for 4 inches (or desired length to crown)
