Thanks Erik and Doug.

Doug - the edging, which I thought would be a nightmare, wasn't in fact!

I used a watercolour pencil, dampened the end and coloured an edge.

I then dampened my finger and wiped the edge which gave me the light colour. Then quickly, while the edge was damp, I went to the spots that should be dark and retouched with the pencil. As the edge was damp, the watercolour came out darker. Done!
