I bought one a few years ago and hung it up to use as a design wall for awhile. I was working on something that was a certain size that should have fit but didn't. Weeks had gone by before I noticed that the batting was 4 inches shorter than the package said. I had kept the package, so it wasn't just my memory failing. By that time I'd had it too long to take back to the store. I thought the batting was okay, but I wouldn't buy it again after that experience.
It should be said that Pellon makes several products that may be considered different kinds of batting. The one I'm talking about here was a cotton quilt batt that looked similar to Warm and Natural. I don't remember the exact name of it. The one I bought may have been a fluke at the end of a run or something,. I think you should go ahead and buy it if you like it, but be sure to check the measurements right away.
