I was working on a tight budget and organization in my shop was in dire need. So I spent less than $10 specifically towards a project to organize my shop. The goal was to make something to organize my shop very cheaply, to make something that could be made and changed easily, and to reduce some of trash. In the end, the project filled all of my goals very satisfactorily.
*THIS PROJECT HAS THE POTENTIAL TO COST NOTHING*
I spent less than $10 specifically towards this project. Almost everything was scavenged, recycled, or reused. But everything doesn't have to be scavenged; most of it can be bought at a standard hardware store or even a supermarket.
