Chain Painting...

If chain smoking is using the smouldering stub of a cigarette to light the next one (not that I condone smoking in an way, you understand. Unless you're a bonfire, or something), then chain painting is a fairly reasonable description of what happens when you use up the paint left over on your palette after you've finished one painting to start the next.

Which is what I did between the first two triptych panels...

And what I'm doing now. After the third panel (the light's rubbish - photograph at the weekend, promise) to start an otherwise unrelated painting!

But I think the palette might need some extra paint...
