At the urging of her adults sons, a dear friend is going through boxes that haven't been opened in more than 20 years. Yesterday, we went through several boxes of crewel and/or needlepoint wool. The single ply and stranded Appleton-tye wool was in good condition. However, there were small spots of mold/mildew on many of the spools of wool (one ply, somewhere between the thickness of 3 and six strands of floss) that had been stored in plastic bags.
I am now the owner of more than half of that wool because it might be great for punch needle work. Is there a quick, painless and inexpensive way besides unwinding past the damaged area to insure that the icky stuff disappears or doesn't contaminate the whole spool?
