if you check the downy quilts for kids web site (or the instructions that come with your kit) it tells you what MUST be included on the label- and the label is a MUST. the Linus quilts i think are less- specific as to what (if anything) should be included...
it's been awhile since i made my last one- but i think some of the items to include on the label is:
the name of the quilt-
your first name
city, state, country.
i also add fiber content- especially if i use poly blends, or batting other than cotton
