I then stippled a base coat of light blue fabric paint on the edges of the rose petals.
Then using black fabric paint with a dry brush I dragged black from the base of the petals. I still wanted to keep some of the white and not obscure the blue.
Overall I am really pleased with the results and the photos don't do the bouquet justice to how other worldly the flowers look.
I am now going to try the technique on a larger scale to make my costume. I have a very old lace dress that I am going to hand paint to match. I'll post progress photos soon!
