I did this watercolour painting by masking out the horizontal and vertical lines to give the impression that it was painted on tiles. The inspiration for this came from the tile paintings which are common in Portugal, where we lived previously. I'm unsure at the moment how it would be best framed to keep up the pretence that it is painted on tiles. The colour used is French Ultramarine.
I suppose I ought to mention at this point, that four of my very short stories have been published in a book entitled 'FLASHBACK 2010' which is available HERE
