I don't usually paint in series, preferring to do different flowers as the mood takes me, but I have recently become just a little bit obsessed with lacecap hydrangeas. I've experimented with different papers and new ways to depict the delicate flowers, learning something each time. Strangely I started with the largest, a half sheet of hot pressed Artistico, and have got progressively smaller.
The second attempt was a quarter sheet of Whatman, a very different paper.
Third, and last for now, a smaller study in analogous colours, measuring just 10" x 7". I think this is my favourite so far.
