here's an interesting news story regarding quilts, flooring, and a lawsuit.
paula nadelstern, a famous art quilter, had heard that the Hilton in Huston has a carpet that was make from one of her quilts.
she filed suit and won over copyright infringement.
it was a really important case as far as quilt artists are concerned because her quilt was made with 3rd party fabrics, and most of us do, and since the 3rd party fabric already has a copyright further copyrighting doesn't apply.
i started making my own fabric when i heard about this lawsuit a few years back.
