I also had to wash my entire stash. My autoimmune syndrome was affecting my lungs and I also was having blisters on the palms of my hands. My pulmonologist asked me to stop quilting for 3 months to see if that was causing or exacerbating my problems. The blisters went away and my breathing improved. So, I washed everything and yes, I dealt with all the strings. Now every fabric (except charms and strips sets) goes immediately to the laundry room. I wish you healing and renewed fun with your quilting; it will be okay.
