UK (or England in 1200) was definitely a wool-based economy, leaving us the Wool Churches (http://en.wikipedia.org/wiki/Wool_church) and the Woolsack still sitting in the House of Commons.
how do you even make clothes
Tailoring is a thing. You'd learn patterns in your apprenticeship, then tailor to the body of the person who will be wearing it. Basic outlines would be marked in your workbench for daily use, but obviously the exact size needs to be adjusted.
Thanks for that link! I also kind of wonder what the non-tailor traded that tailor for their garments, and where the tailor got their tools/equipment/raw material, the whole shebang, so to speak.
As others have said, back then, everyone worked as much as possible just to get by, so I guess if you weren't a tailor, you were X, so there was something you could offer to exchange.
