I work in a tiny, leaky, antique shed. Workspace is a precious commodity that keeps getting taken up by scraps and in-progress pieces and just plain junk. From time to time, I really need new ways to store stuff and I have referenced this webpage for more than one really great, "I can't believe I didn't think of that!" project.
Here's a few projects on the page:
The multi-layer pantry cabinet tool chest
The expanding wood and parts rack
...and my favorite, the folding work table.
See all the projects (and some amazing dad jeans from 2009) over at Popular Woodworking.
If you need more details: I found an Archive.org PDF of the entire article that details all the projects with cut lists and more.
