We call it her Fiona hat (as in Shrek).
She is not a fan of the name but... it has stuck.
Pattern I used is Bzz Hat for Queen Bees by Anne Wolfe (rav link) from the Stitch 'n Bitch Nation book.
I modified the pattern to suit Ann but only to change the fit. I added to the width and some length.
Gauge was different than the pattern suggested also... I used a size 8 needle.
It is her go-to bum around the house, everyday hat this year.
