Here is another section of my downtown mosaic on mesh in progress
Here is a section featuring a woman shopping downtown. Once you have your image under plastic pulled tight, and mesh laid over that, then you can begin nipping tile and gluing it onto the mesh. I printed out 8" x 10" sections in color to refer to because in certain parts it's hard to see what's going on in black and white. I use Weldbond glue, fiberglass mesh, and frost-proof porcelain tiles and stained glass because this is going on a buildings exterior and you need to use exterior grade materials. I used a black Sharpie pen to outline on the mesh where I will be cutting the mesh into pieces. That way I know not to put a tile over the line so I can cut it out later. From what I hear, the pieces should not be larger than 18" or the weight of the tiles will pull the mesh down if you're adhering it to a vertical surface.
