What's the best way to mount wood boards to a wall (for shelves), maintaining low visibility and high strength?
I was thinking about making a custom shelf for all of my DVD/video game cases. I have very little space in my room and would like to make use of my walls. I'm going to measure everything and build the actual shelf myself using wood boards (sanded, cut, etc.). The only problem I have is mounting it to my wall. What I'm wondering is what is the best way to mount the "shelf" to the wall in the least visible way possible, while still maintaining very high strength (so that the shelf doesn't fall down)? The shelf is going to be pretty bland: no funny cuts or weird shapes, so finding a way to mount it shouldn't be a problem.
