I love this hanging so much! Putting the pics in is a great idea.
It definitely gave me the thought that I would like to make another house wall hanging (it's a very simple house block w/6 windows) only add a pic of each of my family member in a window and then perhaps sew in the name and birthdate of each person. I think I can do this fairly easily ~ something I wouldn't attempt (but I know someone out there would) would be to make up a family quilt for a grandparent and have each house represent a child and their branch of the family. Just some thoughts that YOUR quilt inspired!!! :D
