We started by blocking out a landscape or seascape on a large canvas - in acrylics - then masked off the parts we didn't want to throw paint at.
Mixing up lots of paint
we turned the canvas on its side, then threw the paint on to the canvas using a largish brush.
The results are quite interesting - marks you couldn't achieve with the usual method and happy accidents galore!
Now we need to finish off the rest of the picture...
