I don't think it's the bins. I have the same issue with "off season clothes". I've always had to wash everything before wearing it at the change of the seasons. Maybe dust mites or something gross like that?
I wondered if I could tumble them all in the dryer awhile if that would help. I have 70 10" squares ready to sew into a DHG. But I can't even think about handling them.
So is that how people manage their stash? Have to wash it right before they use it?
