I just finished a pismo hat tonight and it took me FOREVAH!!!
Seriously, off/on for a few months, in between other projects. And right at the end I couldn't take it anymore so I started decreasing every 3 rows instead of every 4 rows, and fastened it all off when I still had 30 stitches remaining. So now it's got a big (well, 1/4" probably but it looks big) hole in the top. It is VEEEERY CUTE though and if I don't feel like wearing it myself I'm sure my son will love it.
What about the coronet hat
from knitty in a manly color??
