does anyone know where I can get some navajo cedar ghost beads so that I can do some beading

I do not know if they have one, but here is a great place to try

I think the 1st one is the most likely to have what u want. The webs site is really hard to navigate, so it is best to order a catalogue, but u can try. Do not give up if u cannot find it. The search terms r not very friendly. On the second one I do not know if u can shop without a catalogue yet.

This one the website is good

There is also http://firemountaingems.com

And never forget ebay for those really hard to find items. I found something I had been looking for all over the web for on ebay. I sometimes have to buy from overseas, but u should not for something Native American. That would be rediculous.

I have a couple of suggestions.you can look for a local powwow and if nothing else you cal talk to those there to find out where to get the beads.
Or you can search native american beaded jewelery and contact some jewelers for some leads.

Good luck!
