I built 2ft wide 16ft long shelves along two walls of my garage 6ft1in off the floor so not many people could crack their head on it.
I piled everything in plastic rubbermaid roughneck totes and labeled the sides before I threw it up there.
My workbenches werent' cheap, but they kick ass.
Welded 1x1 and 2x2 steel square tubing into a frame 30" deep, 36" tall, 90" long and covered the top and shelf with 17/32nds plywood that I bought with a gift card from lowes. I can probably set a car on them and they would hold it.
You can see the shelf in the background top left of the pic, and the fresh finished bench in the center.
I store alot of tools under the benches and they opened up alot of space in my garage.
And I can actually have a place to work thats not scattered all over the hood of a car or a folding table thats about to cave from the weight of a transmission.
