Thanks so much for the many suggestions.
Sierra, especially many thanks for your comments as I was not at all sure I had been true enough to the African concept. I have very little personal knowlege or experience to pull from. I just let my heart and my stash guide me. Another friend has suggested the name African Cascade because of the way the size of the squares cascade across the quilt diagonally.
KSellers, I am very touched and moved by how you see the quilt's message. You have put into words what I was feeling as I made the quilt, but couldn't explain.
I am so torn by the choices, so many good ones and good reasons for them! My sister has made 2 trips to Africa, so I think what I am going to do is give her all the choices, and a photo of the quilt, and let her have the final choice. I will wait a while, in case any more such excellent suggestions come in.
You are all soooo amazing!!!
