All The Shelving!!!
If you have a very small space and a lot of stuff to store the easiest trick is to build up instead of out. Shelving is inexpensive, easy to install, and convenient for displaying all of your materials. Check out the incredibly messy office on the left and then compare it to the office space on the right. You might need a stepstool to retrieve some items but the lack of a messy desk will make up for that extra step.
