Brian, they are meant to be used in conjunction with crown molding to give crown molding more depth and relief. Outwater is the supplier and you can check it out at www.archpro.com. I did not mean to imply that you would apply it over the molding, but I think that this was the product that Peggy was thinking of. There are many other sites on AltaVista--search for Lincrusta--that show how to use it. My daughter, who has a 150 year old farm house, is going to use it in the parlor and library to give the look of more ceiling height.
