It's also cheaper to buy a nice quality bedsheet to use than fabric from a bolt. That is if you want a solid color which I think I'm going to be forced to go with. I can't find anything in my stash to go with the print or pale champagnes and creams of the fabrics used on the seats and window boxes. Oddly enough I have one large cream color oversheet I never used to back a quilt with. I may end up using that.
I hadn't seen anything mentioned on any of the sites about problems with the cotton crop.
