I finished the 3 horse head mosaic. My husband cut the board that I used. After I finished the design, he helped me grout it. I ended up using Almond - Non Sanded Grout. After the grout was dried, I cleaned up the surface of the mosaic. Sealed it with high gloss art varnish. Then my husband hung it on the wall for me. We did have to rearrange a few pictures to get it where I wanted it.
