Thanks for the ambitious comment. I guess for me, if it's worth doing, it's worth spending way too much time and effort on. :)
So, DK weight cotton yarn possibilities:
http://www.yarnfwd.com/youngtouch.html looks nice and has some nice reds, browns and gold/orange, but no deep red/maroon.
http://www.theyarnco.com/brand_display/153 is nice, but the cranberry might be too pink.
Sport weight seems to be all too pastel for what I want to do.
