did you try vacuuming the hair or using blown air to remove the dust off of the hair. Dmc floss from 30 yrs ago was good, so I wouldn't worry about that. Now we all know why you use good fabrics in our projects, we may have to wash them 30 yrs later. My son is 26, and about 20 yrs ago, he said he didn't want a quilt for Christmas. when I put him to bed on the 21st, he said he wanted a quilt. I too was up to 2 am trying to finish his quilt on time, and finally finished it in the wee hours of Christmas morning.
