This particular piece is called Blue Wren and is a design that I have previously used as a lino print as well.
So I usually begin by having an idea and preparing a board a suitable size and shape. The board is cut to size and then the back and sides are painted to seal it with 3 coats of exterior paint in a neutral colour. The side for the artwork is left raw so that the glue will stick well.
Then I draw out the design using a permanent marker. All my drawings are done freehand. Sometimes I will have a paper drawing of the design but usually I just draw straight onto the board.
Once I am happy with the design then I will begin selecting the tiles I want to use and begin to either cut them, or smash them. Depending on the design, it is usually a combination of both because this gives the pieces more contrast between the areas of colour.
In this mosaic I have carefully shaped most of the pieces for the body of the bird and then used smashed tile for the background. This way you can see contrast in colour and texture.
I almost always use a border and I like to get that glued down first.
Then I just keep gluing on the tiles until the piece is complete. Once all the tiles are on then I can apply the grout.
Once this has dried then I add the hangars onto the back of the board. Another piece completed.
