"Twisted", acrylic demonstration by Sharon Lynn Williams

"Twisted", 11 x 15", textured acrylic on watercolour paper

I did this demonstration for my last mixed media class of the year. It features working on a textured ground, and building up of translucent layers of acrylics. See below and the next 2 posts for the process.
Step 1: I textured the paper with light moulding paste in the centre where the tree will be, trying to be random with the paste, and applying it with a palette knife. The outer edges have gesso and gel medium on them, which were then imprinted with the lid of the gel jar. Care was taken to make sure that the negative space between the tree and the edging was interesting. Remember: Shapes first!! After the texturing had dried and cured for a week, a quinacridone magenta wash was brushed over the surface and allowed to dry.

Step 2: A quinacridone gold transparent wash was then brushed over the surface in areas, and was wiped back in others. Here you can see how the different mediums take the paint differently. The gel is non-absorbent, the gesso semi-absorbent and the moulding paste very absorbent. This gives an interesting quality to the paint surface.


Step 3: Brushloads of green paint were applied with the brush flat to the surface so the paint would be deposited on the high places in a random way.

Step 4: Green folliage applied, along with some browns for the trunk.
