Tube shelves

It’s simple: I needed some storage space and didn’t want to spend more than $15 so I made some shelves out of the cardboard tubes used for concrete posts. It’s got that honeycomb look going for it, can be reconfigured easily, and is easy to build.

Verdict: they of course work (how could they not?) but a little is left to be desired. Load it up with some books and it starts to seriously sag, and not a good sag. A better, stronger tube material would be a major plus.
