I used the Three Irish Girls Adorn Sock yarn, which was perhaps not the best choice. The yarn is lovely, but the pattern would likely show better with a more subtle colorway. I love how it turned out, but certainly if I really wanted people to see the pattern, a different color would have done that better.

As you get to the top, it seem like it's going to be too poofy - like you are accidentally making a beret without any decreases, but it works out fine. It's a very nice hat design.
