I'm currently working on a large-scale mixed media colored pencil and marker drawing. I've noticed some of the colored pencil rubbed off on to another sheet of paper I put on top of the drawing.
I've got a can of workable spray fixative and I was wondering how often I should use it? Should I use it immediately after working on the piece or should I wait till I'm finished? Is it bad to use the fixative too often? Or should I use something else to preserve my work?
It might also be useful to know that I work very slowly and take a long time to finish things. What are your thoughts on Workable Fixative?
