I have done this first study of clouds using canvas board. Ever since my pregnancy I have kept away from turpentine. Now my daughter is four and is away for loger period of time. The medium I used for this painting is 1 part linseed oil, 1 part turpentine and 1 part Damar varnish, I call it solution II. Both my new slutions have same consistancy and only time will decide which I like better. Also using different support gives so much different results, obviously canvas is more absorbing and looks less 'liquidy' even when using same amount of medium.
