well I hope not!
I buy batting on a roll now too because its more economical. I have 2 rolls that I am using now (one is hobbs 80/20 and the other is warm and plush) Then Amazon had a good price on the warm and plush so I bought it.. and its still in the box. Who knows when I will get to that one
in my mind, I think as long as I keep it in a controlled environment it will be fine. My rolls are kept dry. I hope I am right
I do know that a local long arm quilter just bought 7 rolls - she said that is a years worth for her. So I feel like she would know. It must easily last a year or she wouldn't do that
