I have done a couple of commissioned quilts and I put: to and from (auntie to grand niece), month/year completed, city/state where auntie is, then under that (in smaller font or lettering) who constructed and quilted, and, if you are in a different geographical area then the giver or recipient your location. All this info gives the quilt history and provenance for later years. For one woman that I made a baby quilt for she had me also add some sentiment - I don't remember exactly what it was other then it was sweet and something to do with being her first baby.
