I just went to the lost quilt site, and your quilt is the first one on the page giving a description and other pertinent info. Sure hope you find it. I think we should all bookmark that site and check it out fairly often in case we see one we might recognize somewhere, and not even know it is missing by the true owner. There are so many quilt shows all over and someone may try and pawn one off as their own.
I also printed out the Quiltmaker's Documentation page, which I think I will make several copies of and use them for all of my quilts. I have photos of almost all of the quilts I have made so far. Not of all of the UFO's but of all that I have finished. I make sure I label all, and there is a hint on this site about putting your name somewhere besides on just the label. Some really good pointers on this site.
