This painting started off with randomly added layers of acrylic paints and inks then sprayed with water and left to dry. sections were gessoed out and then I highligted areas with black paint. Modelling paste was added around the areas of black paint More paint and inks were added layer by layer and gloss medium added between each layer. Some sections were wiped off to show the existing paint underneath. Feb 18th, 2013, so here is where I am after many layers of paint and gloss medium varnish. I just found out at a demo from Liquitex on Monday night that I should be using the light modelling paste instead of the heavy one that I am using. It makes sense because after a while the weight will pull on the canvas and cause it to sag. I may purchase the spray that I saw at curry's art store to apply to the backing to prevent it from sagging.
