Crocus mosaic complete - with step by step photos

Here is the completed Crocus mosaic - it measures 8" x 8" (20cm x 20cm)


It started life as this...



And here are the stages inbetween...


1 - This is my sketch design of how the finished mosaic artwork should look.

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.
4 - Custom colour blends are created, from the blocks of polymer clay, for the different elements of the design. I roll out thin sheets (2mm thick) of the different colours, using a pasta machine to ensure they are an even thickness. The sheets are then baked to harden the clay.
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.
7 - Acrylic paint is used to colour the tile grout, which is spread over the artwork, pressing it into the joints. The excess grout is wiped off with a damp sponge before it begins to cure. This process may need to be repeated to ensure all the joints are evenly filled.
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.

  6. Thanks to you all for your kind comments. To Lorrene, the reason I did not show how I made the marbled background is because I got caught up in the creation and forgot to take any photos. I rolled out a sheet of Premo Pearl and then, with a mini food grater, grated small amounts of each of the colours I had used (raw clay). I rolled the coloured shavings into the surface of the pearl clay with a brayer and kept playing around until I liked the look.
