My youngest child wanted a Pokéball hat (based on Poke’mon).. so I came up with this design. It is all double crochet. The “button” is also double crochet & is added after the hat is finished.

I can made 2 hats from 1 skein of each colour. Red yarn will run out first. This hat works up in about an hour (or less).

For those wondering…. YES… Row 6 is correct as written:
Chain 3 (dc in next 5dc, 2dc) around, join.

This hat pattern was also published in the 2013 Calendar Crochet (Crochet Page A Day Desk / Box Calendar 2013).
