Simple top-down double-knit hat is finished!

My simple top-down double-knit hat experiment is done.

It took me ages knitting this with my 2mm circulars. Lessons learned in the course of faffing about:

1) Use larger needles. Maybe 4mm or 5mm circulars (and an appropriate yarn for that)

would have made the project faster.
2) If I ever make a hat like this again, I will use an i-cord circular cast on for this project and not a modified Emily Ocker cast-on.
3) This hat was not allowed to be "girly" because it was for DH, but I think ribbing would have been a better move than of stockinette.

The inside of the hat turned out to be a disaster. I blame this on the cast-on, needles-size and tension that resulted. Looks like this will be a non-reversible hat, but at least it will still be warm!
