I've washed and rewashed the batting, but it still bothers me. And it's only this particular kind of batting. I don't think it's been processed too much because I can feel little hard bumps in it as I work with it. The more processed battings don't bother me. Only this stuff. I normally don't have a lot of issues with allergies at all. I get a little bit of allergy problems in the Spring and Fall, but only when the seasonal allergies normally hit. Dust bothers my asthma a little, but only when it's flying around after dusting.
