Always order a fabric sample!
I'd thought I'd found the perfect fabric for my office windows and almost ordered it when I ordered the guest room fabric, but talked sense into myself and ordered samples of the fabric I wanted and one other.
Well, the fabric I wanted was *totally* different than I expected. I had misread the size of the repeat. It's almost 'burlap' in weight. It's "rustier" in color than on-line. I am so glad I ordered the sample since I don't like it at all now that I've seen it.
Moral of the story: patience is a virtue :-) and ordering a sample pays off!
