They have 'amish' garment fabrics downstairs so there might be some wool there??? This place has an entire ROOM of wonderful flannel as well. There is also I believe it's called 'Goodville Fabrics' or something to that effect in Goodville, PA (same general area). They are behind another building. Again, another place that has many fabrics in addition to quilting cotton. Also lots of trims and things. Might be some wool there.
