Not just any batting, but I think I'm allergic to the 100% cotton batting. A friend gave me a bag full of 100% cotton batting that had not been needle punched, so it was a bit more stretchy. They were large scraps, and I thought they would be perfect for baby quilts and small projects. But, every time I work with it, my nose itches, my eyes water, I sneeze and I have to continually blow my nose. I've never had that problem with Warm & Natural, but I buy their needle punched batting, so I don't know if that makes a difference. The cotton/poly blend doesn't do this to me, so I think it might be the natural oils and sometimes seeds that you find in the 100% cotton batting. Does anyone else have these issues?
