I bought an adult and matching kids hat pattern from Etsy from ButterflyTree. The pattern is really fast and easy and the final product is cute and reversible!
The only thing I haven't quite figured out is what kind of interfacing to use to make the brim as stiff a I want. I used 3 layers of extra thick interfacing and it still wasn't quite what I wanted.
The other tip I have is that these are definitely sized on the large size - if you are in between size down a size.
I really need to make a bow or fray flower for mine because it is a little plain without anything. I am excited to make Chase and baby hats too!!!!
