-Is this video I will show you how to make a collagraph plate from a snack box. You can use a variety of materials as both the matrix and the collage itself. Make sure your plate, with materials on it, is no thicker than that of a nickel. If it is too thick damage can be caused to your paper.
-Try and have a good amount of time between when you finish making the plate and when you coat it. In between these steps it’s also advantageous to put weight down onto the plate for a few hours to flatten the materials that were used. If you like two layers of primer can be applied as well. Just let it dry for a few hours between applications.
