I would like to knit myself a very floppy brimmed hat. I have been looking for patterns, but they are for heads that are smaller than mine. I can't seem to figure out the formula for fitting my size 27" head. Yep, a bit bigger than the average 22 inches I'm finding online; I also have a mane of pretty locks.
Anyway, if you know the formula (like for real and not just "figure it out from..."), then do post and share. Remember the ones I'm finding on the internet are for those with hair that is silky and closer to their heads.
