The magenta heart is modeling paste that I added micro-beads and ink refill
In the She Art pic the modeling paste is in the bottom right corner using a stencil and sprayed with a mist.
IMHO I don't think that modeling paste and heavy body acrylic paint are the same. My modeling paste is much thicker. I can see how they could be used the same, but when I use modeling paste I want a heavier 3-d effect and for me it would be harder to build up the paint to get that effect.
