i also include the name of the quilt- care instructions, any information about designer- if i used someone's pattern.or if you have someone else work on the quilt-like having someone else quilt it- that info should be included- or if it was blocks from a swap- if you didn't want to list each person you could at least state the swap..
some of the large quilt shows recommend you actually write all of your information right on the quilt- at the top under the hanging sleeve- that way if someone swiped it you could easily identify it as yours---surprise to them :)
