I finished my Manos Maxima Hat this weekend and it turned out great! I love merino, it does exactly what you want it to. It's so well behaved. The colour distribution is lovely, the texture is lovely, the fit is lovely, and it feels LOVELY! I am thinking of making some fingerless mitts it int next.
In other good news, I tried the hats on a size model, so the pattern will be ready to go very soon! It's not a fancy pattern, it is intended to be a go-to for man hats.
