It is funny because I was thinking about the same thing a day or so ago. What I do have is a metal magnet strip meant to hold smaller tools. I thought although it wouldn't hold all of the bits I needed because it is only about 24 in. long, that it would hold a selection. It is still in the box. I need to find convenient wall space for it.
Let us know how your project works out. My only suggestion would be to make sure whatever you use doesn't tip easily and spill its treasures. Not much more is discouraging than to have to stop in the middle of a project to pick up and sort through the piddly things.
