If I may offer what I would see as benefiting your "branding" perhaps you could draw on your experience in Latin America and present some uniquely Latin touches in your display models. That might prompt some further thought by someone looking to have a custom piece done. If they request a serape type quilt I would see no difficulty in providing it for them. But your display materials should set you apart. I think that's where Dutch was going.
FWIW I know Dutch personally and I really believe he was not intentionally suggesting you were ripping off something that "belonged" to someone else.
