My sense of smell is not all that great. Hard to believe dogs and cats have a great sense of smell when they almost touch whatever they are smelling.
In the summer I keep the hanging bags of moisture absorber in the closet that has my fabric in it.
I pre-wash all my fabric and wash all finished quilts. I use fabric softner also.
I don't donate to any kid outfits. They seem too picky for my time and efforts.
