how would you tile the face of the arc the top bit is easy also how can i get a neat finish where the top tiles meet the face?

Hi,
I take it we're talking about ceramic tiles here?
I'm not a ceramic tiler but as far as I know the only option is to cut some tiles into narrow strips which are narrow enought to contour around the curve of the stair riser. Cut the strips evenly to the same width to achieve a neat appearance. If its a light coloured tile with white grouting then this can look fairly neat.
Apart from that the only alternative is either to eliminate the curve and re-build the step with an angle...or lay the ceramics up the centre of the stair and paint the borders instead.
