I think that the fabric made in china is using formaldyhyde as a sizing now. I used to get an allergic reaction walking into fabric stores years ago, and I stopped sewing for a long while. Recently I had an allergy attack, and couldn't figure out the cause. Duh, I stopped and shopped a long time in Joann's - I wonder if it is the formaldyhyde, or just the dust. Joann's seems to have gotten messy lately.
