I had been interested in duvets currently on dwellstudio.com - several are Morocco- inspired. However, I just checked out saffron marigold, and they have some lovely bedding choices that are far less expensive.
Perhaps not exactly the right geography, but saffronmarigold.com has beautiful indian-inspired linens. Some of their patterns have a moroccan feel. I've had a duvet cover of theirs for years and the quality is terrific.
