bonus project :-)
First gesso the canvas and use the misters to give it some colour, Use Saffron Yellow on the stencil and next use Arcival ink in jet black to stamp the skull stamp on the canvas. It did not give a very gooed print because of the canvasfrme on the bakc made it hard to stamp. But I liked the effect.
Next use the stencils with the lamp black acrylic paint. and add 2 layers of Triple thick gloss glaze.
