Yes, I'm allergic to the chemicals as well. After 10 years of treatment I can occasionally go into the fabric store.
(2-3 times a year). But I do pay for the exposure. It takes about 4 days of detox cocktails 2x a day to flush the toxins.
So it is a real treat for me when I do shop for fabric.
My fabric is washed with chemical free soap (rinsed in vinegar)the minute it comes in the house.
