It started life as this...
And here are the stages inbetween...
2 - The Pro-Panel block board, that will form the base of the mosaic artwork, is sealed with two coats of diluted Weldbond glue.
3 - The outline design is transferred onto the board, using carbon paper, and then the edges and the back are given several coats of black acrylic paint.
5 - Each piece of the design is cut from the baked coloured sheets of polymer clay. The edges are sanded smooth and the back is roughened with coarse grade sandpaper, to help create a ‘key’ for gluing.
6 - All the pieces are glued in place, using Weldbond glue, and left to dry for at least 24 hours. Minor trimming of some edges may be necessary to ensure neat, even joint lines.
8 - After the grout has dried for at least 24 hours, the tile surface is lightly sanded (with grades 400 through to 1000) to remove any remaining grout residue. It is then hand buffed to give a soft sheen.
