I've made a few frames, like the one on the right. It's made from dishes - both new and vintage. That's what takes the most time, collecting dishes and other fun things to use in mosaics. I included a few marbles and beads in this one too.
A friend who works in ceramics told me that there are discarded pots when a kiln is emptied. I collected a few of those last week and got going on this pot.
I haven't applied grout yet so it will look different when it's finished ... I'll finish it up this week.
