This hat is an amalgam of the Turn-A-Square pattern, which I've greatly enjoyed knitting before, the Purl Soho Simple Pleasures brim, and the Dessine-Moi Un Mouton sleeve stripe pattern. I was concerned with fit, and my diagonally-upstairs neighbor suggested that I could knit in some flexibility by giving the recipient an option to wear the hat slouchy or to fold the brim and have a more fitted look. She recommended a Purl Bee pattern with a long stretch of ribbing to start, which led me to the Simple Pleasures.
Because I was using fingering weight yarn (Plucky Knitter Bello in Pollen with stripes of Heartstrings, Old Copper, Fisherman's Wharf and Bastille), I cast on 140 stitches and then did almost three inches of 2 by 2 rib. After that, I pretty much followed the Turn-a-Square pattern exactly, except that I used an idea for striping from the Dessine-Moi Un Mouton Pattern. I'm in the midst of knitting a Dessine-Moi sweater and have loved the combo of stripes with blocks of the main color. (I actually meant to follow the Dessine-Moi stripe pattern more closely, with some sections of 5 stripes and some sections of 3 stripes, but I forgot to switch to 3 when I started my second group of stripes and decided there were too few stripe sections to make it look intentional if I switched for the third group.)
All together, I'm pretty happy with how this turned out and the recipient seems to enjoy it as well, so I'll call the amalgam a success!
To slouch or not to slouch?
