Cityscape on the River is really a touchy-feely kind of piece as the main fabric I used is an Oriental flocked fabric that I picked up a couple years ago. The buttons stand out much more in this photo because of the lighting than they ordinarily do -- except, perhaps, for the three red leaf buttons on the right side. What seems to have happened is that the buildings themselves attracted the buttons to themselves!
My artwork is mounted on foam core, which creates a light-weight but rigid piece with a wire for hanging and a felt backing. It is treated with a sun-block spray, although prolonged exposure to direct sunlight may eventually cause fading.
