There is also a place in north east Alabama. It is called Hice. They sell scrap bags from their manufacturing of medical clothing. Nice selection of fabric prints and solids. It is a bit heavier than quilters cotton but still good for utility and charity quilts. Believe also they sell it by the 50 pound box on line. I will get more info.
The one time I bought the smallest piece was about 4" square. Usual clothing mfg remnants and cuttings.
