If you often work by adding layers and layers of paper and product to your Mixed Media collage artwork, than you will be quite familiar with the feeling of being at the "end of your rope" when your piece just doesn't seem to work the way you would like. Sometimes, after a very industrious session in my studio when I have tried everything to resuscitate a piece, I find that adding a free wheeling white pastel marks or lines to the work is just whst the Mixed Media collage doctor ordered. Just a little stroke of white does the trick. Since pastel is dry media that smudges, be sure to keep your hands off the work after you have added this element. On the other hand, if you do not love the addition of pastel marks, a damp paper towel can remove.
