I little experiment I've just done on this flat fallow Monday.
I hardly ever use dip pen and almost never get the old watercolours out. But you cannot beat how it looks, the washes, the happy accidents. Or in this case, the unhappy accidents, as I hadn't realised the ink I was using would run when I started to apply the watercolours. D'oh!
What's the ink I need? Is it Indian ink/ Encre de Chine that doesn't run once dry?
