I suppose that's what comes of a novice treading into expert territory! "Coarse" may not have been the best choice of words. You've described the result exactly!

I'm very pleased win the way my little project turned out, actually. I intended this to be a sort of hard use car blanket, of the sort used for spreading picnics, etc. It would certainly serve that purpose, but it is also very warm, wind resistant, and pleasant to the touch.

Aside from the issue of expense, I could see fabric of this sort being used for a variety of purposes.
