I sell wide backing, batting and run a longarm business. I have refused to purchase the cheaper backs, and some Kaufman stuff as it is very loosely woven. As well I do not carry the Hobbs 80 /20 but use Pellon Legacy blended batts. Anytime I get a Hobbs 80/20 from a customer , there is potential for issues. I love the Hobbs Heirloom wool, but not their blended or poly batts. I had a Hobbs poly batt disintegrated to pieces when a customer brought it to be used. Not sure why but it made me cautious.
