I have allergies to dust and molds. I keep a dehumidifier running 24/7 in my basement sewing studio. I also have problems with plastic bins, so all my fabric is stored on shelves behind bi-fold doors. And pre-cuts are stored in file drawers under my large cutting table. My allergy issues are greatly reduced since the elimination of plastic bins. I can't believe those chemicals used in plastic production are any better for fabric than for me.
