I just finished a quilt with warm and natural batting . I did not preshrink for the quilt but... took all the "scrap" batting to soak to preshrink for some table runners , and there was a not so pleasant odor in the batting. It took quite a bit of rinsing to get most of the smell out. Anyone else had this issue?, and what is the cause of this smell? I am very concerned about the quilt as the smell will "bloom again" in humid weather. I have been using warm and natural for years and never had this happen. I recently stocked up and now am concerned about my generous reserve of batting.
