You will need to know how to make a hdc foundation row prior to beginning your hat.
Your hat will begin at the bottom of the hat edge

Special st: the crocodile st is worked over the 2 dc’s that are made together in the 1 dc. 5 fpdc are worked around the 1st dc, then another 5 fpdc worked around the 2nd dc. To work your 1 st, 5 fpdc you must turn your working piece side ways to the right, so you will work your 5 fpdc side on from the top of the post downwards. When working the other side, you will turn your working piece side ways to the left, so you will work your 5 fpdc side on from the bottom of the post and upwards
