I've never made a quillow and am not sure I've even seen one. But I understand the concept - a sort of quilt with a pocket that folds up into itself to make a pillow. Is it even necessary that it lay flat? If the fabrics aren't desirable for quilting, and the quillow isn't finished, and you don't have any strong desire to make a quillow, why not toss the whole thing away and spend your time on something else?
