Yarn arrived 9am - hat knitted and packed up for it's new owner by 8pm (and that includes all the housework and mothering time in between) . Would have been quicker if I'd been able to understand the pattern to start with!
Used the yarn in the pattern - shetland flame. Did size medium and it ft my large head no problem. My glass head is a little bit small- looks better on a human. I think I'll try it in a smooth chunky yarn next.
