I wrote out my Chevron Hat pattern back in 2014, I thought I would make it again. What I did different was that I added an additional 14 stitches, I started with a small hook that the size I had stated in the pattern, then I went to a larger hook after the first six round. The only other thing I did different was did an addition row of decreasing 2 single crochets together to close up the hole on the top. I have additional ideas on doing another version of the hat.
The pattern for the hat can be found here.
