1. Choose a consistent organizing principle by keeping all your frames the same color and the matte size uniform. Another idea : Print photos in black and white
2. Arrange frames on kraft paper on the floor, largest in the center, keeping a distance of two to three inches between them -Trace each with a pencil.
3. tack the paper to the wall and hammer nails directly through it for a perfect placement; leave two to five inches between the collage and any doorjambs.
4. Hang scenic, airier shots up high, mix light and dark shots and keep all eyes - whether they're human or giraffe - facing the center to create a sense of balance.
