I found the purple tray on clearance for under $5. The mosaic pieces are dishes that I found at the Texas Art Asylum for under $4. I grouted it with black grout and then added an acryllic coating to finish it off.
The only issue I had was with the acryllic coating. Lots of bubbles! I used my blow dryer to heat it and that helped get rid of a lot of the bubbles.
