I'm not sure what colors you want or need but try Jelly Roll Fabric; they only sell jellies. They have 20 fabric rolls of 20 different fabrics and their prices are very, very reasonable. I think one jelly is about 12 or 13 bucks. (Not affiliated, just love the quality of fabric and prices of that shop.)
