Thanks everyone for your kind words!
Merry - I didn't find the pattern hard, but it was slightly tedious.. since in essence, you are knitting 2 hats in fingering weight yarn. The pattern is written in 1 size only. Mine came out a little tight because of my floats, but it still does fit an adult head. If my floats were good, I think it would be just right - not too tight and not too loose. I've seen other versions on Ravelry knit with heavier weight yarn, so you can always try that too.
