Among other things I've been exploring dimension on the surface of my canvases by way of  light weight modeling paste. In some cases I'm embedding materials or found objects into the paste before it drys. I've been having a lot of fun with this. 

The photo shows an area of a painting in progress. I have incorporated sea glass as well as sea shells creating a relief area representing the rocky reef. Other objects within this painting are jewelry and coins from a long ago sunken  ship!

I'll post full image when completed.
