I think Penelope Dullaghan's mother was onto something when she wrote this (most mothers are very bright, you know). When I read Penelope's post the other day, I had to paint it into my sketchbook. A good thought to keep note of.
Watercolour often doesn't work on Moleskin sketchbook paper, it mottles along the surface and doesn't really grab onto the paper. But in this case I like the effect. Does look rather bloomy, doesn't it?
