I have made this hat from acrylic DK weight yarn and they were quite quick and fun to make. The only part that might be a little confusing in this pattern is the “Front Post Double Crochet” technique that I have used. There are a few Youtube tutorials which are useful for learning this technique.

If you find this too difficult, it is also possible to replace this with just “DC” and make a normal hat. I thought that adding the cute ridges at the front would be fun to imitate his forehead wrinkles.

I made both hats with one 100g ball of yarn and used about 3/4 of the ball.
