I have encountered sneezy, achy, runny nose, headache problems with some fabrics. I do have lots of allergies but have had them under control for a number of years; however, I keep my nasal spray and inhaler everywhere, like, the car, purse, sewing tote, bathroom...
Remember these fabrics are from overseas, in warehouses, containers on ships, in trucks, on floors, wrapped in plastics, full of dyes and all types of chemicals, etc, etc, etc...
