Followed pattern exactly as written, got gauge on 6s although the fabric is a bit looser and drapes more than I personally like - as others have noted about this yarn, it knits much closer to a DK than a worsted. The recipient is happy with the effect, but if if I’d been knitting for myself with this yarn, I would’ve dropped a needle size and done the math to get a tighter fabric.

The pattern was clearly written and although I couldn’t understand HOW it was going to work, I just kept chanting “trust the pattern, trust the pattern” and sure enough I eventually got a hat that I still didn’t understand but that looks like a hat once you stick it on somebody’s head. I did put in a couple of tiny tack stitches on the crown as I was weaving in ends. The recipient is delighted with it and it looks very cute. I might make one for myself, but I’d use a different yarn. The actual knitting was very straightforward and easy aside from the mobius cast-on, which I just don’t do often enough to have memorized. I did most of it while watching tv and in the car and finished it on Christmas Eve.

When you get to the part where you start working with a second needle for some of the stitches, you may want to disregard the part about not over-tightening as you switch needles. I had an AHA moment when I figured out what was happening there - it’s the same as doing socks on two circs, only twisty because it’s a mobius! I normally give the yarn a little tug every time I switch needles when I’m knitting on two circs or on a set of DPNs; I didn’t this time because the instructions warned against it, and ended up with very obvious laddering in those spots. In wool, it would possibly have blocked out but the recipient won’t give it back to me long enough to block it properly, so we won’t find out until the first time it needs to be washed.
