Yes, it's not that shirts are complicated, it's just that there's such a lot of hemming involved. Women's caps are similarly deceptive in that they look like you could run them up in an hour, but really there's days of rolled hems involved in the ruffles.

I was at Detling too, but I was there with Regia Anglorum. I know what you mean about the cold! I've just finished making a semi-circular cloak as a result of it :)
