In the binding once I embroidered Sweet Dreams, Sleep tight, etc on three of the edge. And for a "tag" people put who the maker was, the year and why it was made. I don't know if there are any rules, I also include the pattern and who designed it as somewhere down the line someone will ask who designed the pattern..............mostly I think you can add what ever you want. I also include my city............not that my quilts will last until the next century. But as I have purchased some antique quilts I have wondered the location.............calla/Sue
