The quilt will probably wash just fine....its the embroidery thread used for the siggies that I'm worried about! I would gently dip one in some water and check to see what happens. I might actually send this one to the dry cleaners and explain all about it so that they can clean it for you. I would also be sure to tell the giftee.. how to clean it for future info.
Its a cool quilt! I'd hate to see anything happen to it!
Editted to say...Duh...I posted then scrolled backwards and read Prism's post...I agree with her...maybe your washer is the way to go.?? You could talk to the cleaners about it...I have lots of faith in GOOD ones.
