I use Hobbs 80/20 batting and like it very much. My quilting is almost exclusively for charity, and I appreciate their low charity batting price for a roll available with 5 UPC's.
A year ago the National Ranching Heritage Center (located in Lubbock, TX) featured exhibits and seminars on the subject of quilting. I enjoyed the batting presentation by a representative from Hobbs. We were informed that although some of their fibers are purchased from outside of the country as needed, they purchase as much as possible in the U.S. and have a commitment to not out source labor.
