I went to look at my roll of batting and it still has the tags on it. It was a commercial roll (so 25 yards which is about 6-8 quilts), I bought it when I had access to my friend's long arm. I got it on a great sale from an on-line discounter (It was under 200 delivered), but this seems to be the manufacturer:

I judged it by ounces/length, this is 12 oz per 100 inches.
I was very happy with it, down to one last top remaining
Not sure what I will do next. A commercial roll is a lot of batting to commit to, and store, and I was lucky that it worked out for me.
