Yes, label -- that adds to the value for the type of person who is likely to buy a quilt at an auction. I've been seeing people use fairly minimal labels but with a link to a blog or website where they chronicle the process of making the quilt and all the details, inspiration, pattern, fabrics, meaning to the maker, etc -- I like that idea. It gives the quilt a lot of history and added interest making it very unique, but it doesn't get in the way of the function or appearance of the quilt with too much "stuff" on the label.
