I have been following this and guess it is time to jump in and admit I am clueless about a couple of aspects of the technique. I have been using an aqua brush and watercolor pencils - am feeling a bit disappointed because the cs often "buckles" because it gets damp. Does this happen with Prismas and OMS?
one of my other questions - when using OMS - do you just dip the stump into the liquid and gently rub over the previously colored area? Sorry, I simply have not quite got this aspect figured out.
