Part of the fun of collaging is the hunt for ephemera. Just the right piece of a single scrap can change the entire composition. Auditioning ephemera is so important. I know right away if a piece is going to work or not. It somehow speaks to me. I guess that has something to do with experience and training. It also has to do with luck. Every once in awhile it is good to go through ephemera stash as there are treasures waiting to be used that you might have forgotten about.
