I'm going to be honest the pattern looks 'African' to me. Now I'll admit I'm not familar with the yemenite culture, so it could be entirely accurate, but I doubt many others would be either so it's more about the 'vibe' it gives off when you look at it.
Personally I think the choice of font for the 'english' text is too thin, you'd struggle to read it from a distance and at least in the case of the bag it stops any potential 'advertising' you might get from it etc.
