I’m certainly no watercolour wizard and it actually excites me that I have copious amounts still to learn.  Watercolour is such a unique medium that really breathes a life of its own, as one soon discovers as paint meets water meets paper.  It can be quite unpredictable and you are bound to get a whole load of surprises, especially when you’re just starting out.  Now I’m sure we all feel the same – that nice surprises can be fun – but sadly with watercolour, my experience has been that more often than not those surprises can be pretty nasty ones.  As a graphic designer, one of my favourite and most used keyboard options is ‘command Z’ used to undo my last action (or stuff up), and I can’t tell you the number of times I’ve wished I had one of those for watercolour!!
