I had an attempt at freehand painting today. I think the flowers are just about recognisable. I realised that I should have used a black background, which would have made it "stand out" more, but I had used my pre painted black oval! (and I didn't really want to have to wait for a black background to dry first.)
As I wasn't completely happy with the white background, before I varnished it I used my dusting brush and some blue distress ink, which solved the problem.
