since thread count in quilting fabrics is much, much less than say, sheets, I wouldn't worry that much about it- at that price it would be worth it to buy enough for one quilt- and try it out- if you don't like the way it feels when it arrives pre-wash it (which generally tightens up the weave if it's loose and softens 'coarseness') and use it for a donation quilt- if you find you love it then take advantage of the price & buy more for future projects.
