Following along with A Workspace for a DIYer with Minimal Time I ran across this in some Instructables "spam" (I signed up for it). I'm sharing this because even with a workspace that is easy to get to, I still find myself with too many boxes and feeling disorganized. I'll likely give these or a variant a go.
To keep track of all your small bits, here is a nice compact way: the "Ultimate Parts Storage", aka a binder with zip lock inserts. You can get to all the parts easily and it's very accessible. The binders can sit on the back shelf next to your other boxes.
The next bit follows along with hanging tools on the wall. If you're like me, I don't have readily accessible wall space. I also don't have a lot of floor space. A variant of the Peg Board Tool Cart that is smaller with a handle on the top would be a convenient tool "box". Your tools are easily reachable yet stored with a small footprint. Another variant is to make it one sided and hang these movable boards on that wall space that isn't easy to get to from your workspace. For a given project you can bring one or two boards over and have all you need at hand.
