Had to overexpose some of the pics since it’s impossible to photograph black.
Really cute hat!
Made minor changes:

• cast on for smaller size to insure a tight fit - 96 st;
• used tubular cast and knit 3 rows flat on 2.75mm;
• transferred on to 3.5mm circs and started knitting 2x2 rib in the round;
• knit the brim for 1.5” instead of 1’’ suggested;
• changed to 4mm, increased to 144 st. for the slouchy version;
• knit 7 repeats in height instead of 8 as it looked long enough, and I’m glad I did. After blocking, it’s plenty slouchy.
