check SEWBATIK.Com If you buy, use LAP1250 in the comment area so they know you found it from me. Great Service, Great Products. Full disclosure: Yes, I am affiliated. But I wouldn't recommend or use if they weren't a top notch company.
Their fabric is wonderful, and the wide back batiks are made with the same weave that quilt-shop-quality fabrics are made. The backs are not that really tight weave that sometimes breaks the fabric threads when on the longarm.
