I haven’t used oil paints for years. I have an unopened box that DH bought me some years ago - not even sure if they would be any good now. But I have never seen water soluble ones and have just looked them up. I would be interested to know what the drying time is for them - one of the biggest problems with acrylic unless you use an inhibitor.
Last weekend, in Rutland, the first statue in Britain of the late Elizabeth II was unveiled.
