<p>A simulated clay tennis surface has a first region (18) tufted with synthetic ribbons (16a) of a first height, and a second region (20) tufted with synthetic ribbons (16b) higher than those of the first region. A granular infill material (22) is applied to a depth which covers the ribbons in the first region, but leaves the tips of the ribbons of the second region visible to form court markings of a contrasting colour to the infill material.</p> |
