Louise kept the same pose for 2 x 2-hour sessions.
I started with a 1 hour sketch in Wolf’s carbon:
Then spent the rest of that session and most of the next on this watercolour painting on an A1 sheet of paper (approximately 2 hour’s work):
Finally I spent the last half-hour doing a quick A3 sized water colour sketch:
The last quick sketch was surprisingly similar to the one before even though it took a quarter of the time to produce.
