I'm surprised some of you seem offended by the information I posted. Chemical sensitivity and allergies to dryer sheets are not an "opinion", and I didn't make any "rule" about using them. I simply asked folks to think about not using them for the health of others. Just because the scent seems gone doesn't mean the risk is gone. As Daylesewblessed mentioned clean white sheets can be found very inexpensively or free through hotels and laundry services, thrift shops, etc. Unwanted fabrics that don't show through can be used as well, or interfacing. I prewash all fabrics before sewing- without dryer sheets. I've seen infants with intractable eczema and rashes, and watched people gasping for breath from asthma attacks. I wouldn't wish this on anyone, and again- who would suspect something INSIDE a washed quilt? Just food for thought if you quilt for someone you care about, or are donating quilted items for comfort. The risk is simple to avoid. Please pass this along to other quilters to consider. Thank you.
