I believe that over a very short period of time, the stuff washes out of the dryer sheets. It's not much after being used the first time, and I hand wash them and dry them again in the dryer before using them. They work so perfect for applique pieces, I don't want to quit using them. A few people are sensitive to products like that, so if making a quilt for a specific person who has that sensitivity, then I wouldn't use them. But for most people I don't believe the scent issue is an issue at all. Use common sense in all these things. It's like baseball stadiums saying they're going to stop selling peanuts because someone in the stands "might" be allergic to peanuts. All these extreme measures are just getting to be too much!!
