Thankfully the forum offers lots of information. As I was trying to find out if water mixable oil paints can be diluted with water without affecting the longevity of the finished article I was fortunate to find the answer on the forum. Here http://en.wikipedia.org/wiki/Water_miscible_oil_paint I can now put the present I received from my wife and daughter to good use. It will make a change from the acrylics and traditional oil paints I have been using. http://www.landscapeart.org.uk/en
