first build up a body of work, finding jewish art is actually hard, so there will be lookers. look for jewish people on twitter, - rabbi's, cantors, jewish cooks, look up jewish words like bubbe, zedde (i'm jewish but have no idea how these are spelled) kosher, etc - and friend them. be sure to say in your twitter blurb that you specialize in this kind of art. it would be advertised the same way you do anything else, just target
