I once purchased a queen size quilt batting from Walmart, in a bag. I unfolded it onto my backing and the center of it was so thin and had some holes in it. I had wanted to work on my quilt , and was going to just use it . But decided I hadn't worked so long on the top to put that crappy batting inside. so I took it back . I used my roll of batting that I get from Oklee and just pieced it together to make it wide enough.
