Gauage in the round

So on the Joeli's Kitchen podcast (youtube), think it was episode 39, she mentioned a way to test your gauge for knitting in the round on a flat piece of knitting. See her episode for how to do it as kinda hard to describe (for me at least).
Anyway, I gave it a try today with my Malabrigo Merino Rios on 5mm needles. The gauge seems to match what I need for the cookie jar hat, thinking of this one for myself but will see if I manage to make it fit me on purpose lol Love these colours so much :) Think this'll be a hat for when it's chilly rather than freezing from the swatch but see what the fabric turns out like when done as a whole.

 Happy Crafting!
