Domnaki, you painting is beautiful…in both places. You should try painting directly on the fondant. In my opinion, it is a much more forgiving “canvas” than wafer paper and you can use your petal dusts wet or dry. To color the wafer paper, it would probably help if you used lemon extract or a high percentage of alcohol instead of water because it evaporates quickly and will not cause as much damage.
