I tried One Step Crackle on the above pages. The one on the left I coated the whole thing, the one on the right I just did spots. It didn't work I think the plaster absorbed it.Watercolors and a micron pen work great on sanded clear gesso
These I waxed, since they are for pages, it went on to thick, as it was cooling, I scrapped as much off as I could then reheated with a heat gun. The one on the left has a bit of vintage lace, I plan to do a rub on transfer, the one in the middle I used a rubber stamp. The one on the right is watercolor, acrylic, scratching and wax.
