what kind of information should you include on your label. i don't think there is such a thing as too much information on a label. the very least should include the maker's name and the year made. i read an article about quilt labels not too long ago and they suggested writing your name in the seam allowance under the binding or on the quilt back under the hanging sleeve. that way if you ever have to prove it's yours, you can just unstitch that portion to reveal your name.
you can also include such information as why it was made (birthday, graduation, special occasion), the quilt pattern, who it was
