emblibrary.com have alot of designs if you have a embroidery machine. You could put that you made the quilt for her graduation; the date, if is quilted by someone else that is normally included. Some people put how long it took to complete the quilt and some even put the laundry instructions on it. It really depends but the important thing is I think, name of person making quilt, for who it is made, reason why (if for special occasion) and the date. You could also use your own label but use a permanent pen to put the info on it.
