That is a very good question. I'm sorry, but there is no easy way to answer it. The correct answer is, if it can be identified, then you need a property release. For instance an Apple I Phone with the round button at the bottom. This is a part of the I Phone design and cannot be duplicated without a release. If the cloth napkin is so distinct, that the manufacturer can be identified, then you need a release to commercially use his design or property. If it looks like every other napkin and shows no vissible design or pattern then the design owner cannot be certain that it is his napkin. Stay away from identifiable markings, shapes or designs.
