Hi, I recently decided to go back to doing beadwork. It used to be a real passion but I set it aside for working on the computer (both are hard on the wrists and fingers) I used to sell my bead work and I agree that wearing it is a great advertisement-also where you wear it. Going to craft fairs, etc to check out the offerings is great but also if you have on your own stuff, people ask about it. I was very flattered last year when I went to an upscale pow wow wearing my bead work and several people asked me if I had a booth there!
I would suggest too you check out the forum on Bead and Button. There is a huge community there and selling work is much discussed. It's at www.beadandbutton.com
I haven't tried creating a website with my work but I agree that seo is very important. Also, on the bead and button forum you can add a sig and photos of your work there as well. It helps with the traffic.
