Susan,
I store all of my photo examples in a plywood cabinet that my husband helped
me build. The box is about four feet tall by about two feet wide. I
divided the rectangle in half by placing a shelf in the middle. We then
placed plywood insets vertically about every four inches. I place all of my
examples of portraiture in one space, night photography in the next and so
on. I then cut strips of cardboard about two inches longer then the depth
of the cube. They work like tabs. I label them and they stick out just far
enough to see. This way I can put more than one subject per opening. It
has been great....but a bit on the heavy side! I just don't move it!
