I'm slowly getting the hang of Aquabord's characteristics in a wet-into-wet application. You can see the difference between the larger fall in the foreground and the upper petals (on irises the lower petals are called falls).
I had painted the fall first and was still struggling with the unfamiliar surface. Then I moved into the upper petals and there, in a smaller area, I started to get the hang of things. I then went back into the dominant fall to improve its look, but I'm not sure that I managed that.
One observation so far: the colors are definitely vivid. You can see the underlying layers of permanent rose in many areas, so there is a sense of depth, but I prefer the textures that developed in the upper sections resulting from a single mingled-color wash. The texture adds to the ruffled look that characterizes this particular bloom. Once the paint is down, it seems difficult to go back in and recapture that effect if you've lost it.
I'm tempted to wash out one area as an experiment, and then see if I can recapture the texture with a fresh application of paint. I'll keep you posted.
