Hi- here is a link to a gal who sells fabric on ebay. She has a private website that sells kits, layer cakes, charm packs and jelly rolls. Her current special is Marble Jelly Rolls for $20. Each roll has 40 strips of fabric, 2 1/2 inches wide. You can choose from bright, citrus, warm or pastel. I've bought a lot of charm packs from her and the service is outstanding.
