To start painting, I sloshed on a very wishy washy background using watercolour paint.
I left that to dry and then sketched in the flowers and stems using water soluble pencils:
I then painted in some translucent background leaves/stems using watercolour paint, and painted the flowers (except the centres) using watercolour paint over the soluble pencil (the pencil and paint merge together):
I finished off by painting in the yellow centres of the flowers, then masking them off and adding paint spatter. I also cropped the picture to a nice card-friendly square shape:
It's my friend's birthday this week so I might make a set of little notelets as a gift for her.
