Easy to knit bulky hat pattern using a 3 row repeating pattern,
Easily modified to fit and size by using multiple of 10 and doing the 3 row repeat more or less to adjust the hat length,
I used one ball of Lana Grande for both the size small and medium size, but any bulky weight of your choice will work, size 5.5 mm and 6.5 mm needle with 16 “ cable or DPNs
Size small will fit a head circumference of 16-18”
Medium-19-21” large
21-23”
