This little portrait is on an Art Spectrum Colourfix ATC card. There is a white border around the surface - all the Colourfix paper has this border - very helpful when you frame your piece. Such a wonderful surface to work on - Colourfix is great for oil pastel because it has just enough grit and accepts many layers. It's quite a challenge to get a picture on such a small surface when using unsharpened oil pastels, but this practice keeps me from being so tight and helps me focus on the essentials of the drawing. It's 3.5 x 2.5 inches - thanks for stopping by!
