I create bead jewlery based on Native American patterns. In doing this I have
often thought of the ethics involved in recreating folk art of differnent
cultures. When I give jewlery to friends (I don't sell them) I let them know
where the pattern was thought to have originated and what nations practiced
that particular type of beading.
I think if your going to base your work on the work of another culture it is
your responsibility to be informed. It is an issue of respect
