I have successfully used cotton drapery samples in quilts and had good results. Most were polished cotton and when washed they lost their shine but have held up well. One I made for my mother in law when she was in a nursing home and it washed in their commercial machines many times, after she died the quilt was returned to us and was still nice. Some of the bedding may work for batting or if sheets could be used for backing. As long as it is washable it should be fine. It works best for machine quilted items. Other things you could use the fabric for are bags or "designer" storage boxes. Good luck.
