I've done mosaics for years. I have numerous tables around the house that I've done. I've sold lots on ebay.
I take a break from mosaics during the winter because it is too cold to sit outside and grout and don't want to do it inside.

I use stained glass and plates that I cut up. What I don't use or don't think I'll use I sell on ebay. Somebody can always use my extras lol
