A specific dilemma: I found some great tablecloths at a recent estate sale; they looked to be linen, but now I realize they are polyester/cotton. I had thought that I would use the fabric to cut down to napkin-size, dye them, and embroider them to become the new napkins for our friend's wedding gift. Question being: can a poly/cotton blend be useful for a durable, nice, formal napkin? Are they going to last? Are they going to pill? Are they going to dye well?
Is there some source for answering these questions? An online bank of knowledge would be tremendously useful.
