Notice the tacks holding pieces down in the painting. We can use glue (white pva based such as Elmer's works), acrylic medium or tacks ourselves. It may work well to work on cardboard if you are going to collage and paint together with tacks. You can also use these as collages to work from to draft the direction of your painting.
