As landscape painters why are so many of us obsessed with bottoms? Why do we feel the compulsion to describe everything in minute detail? It's not necessary and in fact detracts from the overall effect in a painting.
I have cut out some of this composition so that we can get in closer to view the relevant bits. Note the drystone wall on the left, the white walls of the buildings and the small gate immediately to the right of the barn, and how I have not rendered a definite bottom line in each case. By omitting this I have endeavoured to make the effect more natural. Usually I only paint in the top two or three bars of a five-bar field gate. You can see that for the right-hand hedgerow I have indeed given it a fairly distinctive bottom, probably a minor aberration when I was desperate for coffee! It's not a great problem as it is in the distance and the bottom part of the hedgerow could be softened off with a damp brush.
So watch those bottoms as you'll get a more natural effect if you keep them soft. Hard boundary lines around a feature can make it look cut-out, rather like a garish sticking plaster on a donkey's ....er, bottom.
The watercolour was painted on the fabulous Saunders Waterford 200lb rough high white paper in order to make the most of the textures on the hillside.
