9 rnds of ribbing. Transitioned from a 4.0mm to the 6.5mm by using a 5.0mm for the second to last ribbing round, and a 5.5mm for the last ribbing round.

I ended on a Rnd 5 because I was at 8” and didn’t want it any taller.

Total weight: 102gm (had to use a bit of a second skein).
8.25” across bottom edge when folded flat x 8.75” crown to bottom edge.
