Did you take a photo of it? I have seen on this quilt board pics of quilts that are "missing". Then the board members keep checking Craigslist or Ebay to watch in case it is being sold.
So sorry for your cousin and your loss. I know that I would be devistated. Could we send you blocks so that you can make another one? I would be happy to send a pinwheel block. Let us know. Yolanda Wood River
