This approach to collage comes from my good friend Donna, and I have used it for my own work in recent years. 
The idea is to cover the surface, initially, with an image cut into strips to reduce bubbling. Then you overlay with images chosen to produce the concept or visual you intend. It’s an accessible process that lends itself to unlimited variations. You can use your own photographs, copied onto 8.5X11 copy paper (Capital Copy can help you with that), or magazine images. We will be working on 8X8 inch wood panels, so your images need to be large enough to cover, or you can use a mix of images, if you wish. Magazines will be available. No experience necessary.
