I found this heirloom quality quilt at a garage sale over the weekend.  So surprised that anyone would dream of parting with a quilt of this quality that their family member had made.  It is quilted so close with the smallest stitches, the applique is just perfect.  I used to piece and quilt before my eyes went bad - I know how hard this is to do, I was never able to do this type of applique.  When I bought it the lady said they found it in a box from an auction purchase.  It is old and needs a really good cleaning, but scared to ruin it.  Any tips for safely cleaning this?
