I had some black solid fabric, bought in a Lancaster quilt shop during a trip to the USA, fray so badly when the top was washed that the top was in danger of falling apart. Very disappointing. I used what was left to make the inner layer of cat beds. There was simply no point in endangering other quilts with it.
Unless I have an iron-clad reason to buy looser-woven fabric, I avoid it like the plague.
