These are two small canvases that I worked on yesterday. I used a modelling medium on them to build up textures One had leaf shapes built up on it, and the other a spiral of shallow spikes.
I also bought some brusho. I’d never used it before. It’s a dust or fine crystals that you can either sprinkle on a wet or damp surface or sprinkle on dry and then add water. The colours change when you add water. For instance lemon yellow looks orange in the pot. You also only need to use tiny amounts. I ended up with a paper plate under the canvases to catch the drops. I tried to get the colours to surround the raised sections then used some acrylic colours to delineate the edges of the shapes.
I’ve left them with Etruria Artists at the warehouse to dry out.
