          | A 4 metre garden border based on
            an existing low brick wall. I used broken crockery, mug bases,
            tiles and shards of mirror stuck down with a mortar mix of 3
            parts sand to one part cement. When it was dry, I grouted using
            the same mortar mix, and cleaned the surfaces with an old toothbrush
            before the grout set hard. |  |
