...on whether I was discussing the use of 17th Century wigs in "Celtic" lands or in "Roman" lands. If I was discussing say, the popularity of kimonos in 18th century England I would put that under Celtia's clothing thread (Brittania being "Celtic lands"), meaning I would be discussing how a particular fashion (jewelry, cosmetic, etc) trend was used in that particular land. The point would not be where the kimono came from. That would be something I would mention in the post, naturally, which means people would be directed toward the Orient board for more information. But the point of the post would be how the fashion (etc) trend effected Celtia.
But then, maybe I'm confused on the whole point of the group. *sigh* It wouldn't be the first time. *g*
