There was a seller on ebay that was sued for this same thing, selling items made from licensed fabrics, the sellers won because the fabric was made to be used and after it was sold it was fair game. However, now they put that on the selvage to protect the designers, so haven't heard anymore about it. We should investigate and see what is going on with this now. When "we" have some time.
I would think they would be happy to let people make things from their fabric designs and sell it, it doesn't make sense to me because you are not making their fabric or trying to copy their fabric design.
