This little acrylic (fabric paint and pigmented inks) collage study (see Fig. 1 below) was originally created to explore depth using commercial stamps and my own rubbing plates. The subtle, barely exposed patterning in some areas and more pronounced in others made it a successful effort, I thought. See Fig. 2 to see what the work will look like with a 3/4" mat all around.
