Brother Sister Design Studio is a private label brand for Hobby Lobby. "The retailer purchased exclusive rights to the artwork of Debra Bryan of California, who created snowman characters for the Cozy line. With Florentine Noel, Hobby Lobby has a two-year licensing deal for the designs created by New Jersey artist Susan Zulauf." According to the article I read these two started the designs.
I have a couple of pieces of fabric with another OBW in mind.
