Back to the original question:
What I consider to be "good quality" cotton quilting fabric.
It is colorfast. It shrinks no more than 3% in either direction. It feels nice and smooth. It is thick enough to that one cannot see easily through it. (Most fabrics have some "see-through" when held up to bright light!) The design is printed on-grain. It is wound on-grain on to the bolt. It has only a very small amount of sizing in it. It does not need to be starched or sized to be usable after it is washed (although if people like to do that, great - but it does not behave like overcooked spaghetti).
