|Here is the old method. Oh dear does it take LOTS of time.|
Suddenly though, I realized that if I used a black canvas and traced the pattern in white on it, I could save a great deal of time if I taught the painting. The students could concentrate on filling in the cactus flutes and not spend the time on what I realized, now, of painting the background in. This was acrylic and not oil, so depending on the paint color, one, at most two coats would cover the black yet allow artists to dry brush the blending of dark and lighter portions of the painting letting the shapes form out of the dark background. Sweet.
I will have to wait awhile to try this out but I have several subjects that will be perfect to experiment with. I think it would be akin to the what a sculptor faces facing a block of stone hammer and chisel in hand. Rather than chipping away, you are painting a form onto the blank surface. I guess, just like everything else, there is more than one way to do something. Will it work? I can't wait to find out.
