When it's available, I'll post the news here and elsewhere - there will be a charge, because a lot of work needs to go into it; but even so, it'll be a lot cheaper than buying the half-dozen books you'd otherwise need, or signing up to a course of instruction (not that there's anything wrong with those, if you can afford it; trouble is, few of us can).
In the meantime, I have a short article on water-colour disasters - mine, to be specific - in the current electronic newsletter of The Artists Publishing Company, aka Painters Online - www.painters-online.co.uk.
And here is a sample of my latest watercolours, photographed as well as I can given there's rotten light in my hovel, and I can't take the blessed things outside to photograph them because of the foul weather..... Working on an oil at the moment - hoping, as always, that it works out.......
This is the one that featured in my e-newsletter piece - of Niton Down, Isle of Wight, with the Hoy Monument.
