I know what you guys mean.
My LHS all 4 of them dont have much. I got tired of running around from place to place.
This is 20 years of collecting stuff and putting on a pegboard wall. Finally ran out of storing place, so I trippled my peg board storage by only losing 7" from my shop room. I built out 7" and built peg board cabinet doors. Storage up against the original wall, storage on the back side and the front side of the peg board cabinet doors. Look back at the picture closely, see the knob? They open up into the other two layers. And what shop is open at twelve midnight on a weekend. My buddies all the time come over to build, BS, or shop for something they need for their current project at 1 or 2 in the morning. The bins down below are basically the loose items on the wall.

Thanks,
Gunny
