Hat Gauge. How to measure

I’ve got an email that to met gauge for Garden party hook was changed to
smaller size, but hat was a huge anyway.  I was wonder,  because usually I
crochet too tight.  But  then  I found  that gauge measured  NOT correctly.
PLEASE pay attention that if pattern says first 3 rounds = 4” in diameter
(between points A and B) that means that it’s actually 6 rounds (points C-D).
So, actually 3 rounds in diameter = 6 rows = 4″

Also, please make sure that you are using yarn of similar yardage if you
would like to get the same hat measurements. On the other side, if you
crochet loose/tighter, just use any thinner/thicker yarn or smaller/bigger
crochet hook to obtain gauge.

I’ve just add this diagram to pattern. An updated version of Garden Party
hat can be downloaded here.

Happy crocheting!!

P.S.: I’m sorry for the delay with flower pins pattern. I hopefully finish the
pattern today and will release it right after tech editing.
