To the left of the cabinet hangs my table saw infeed support arms, my table saw spline jig, multifunction hold down jig, and a dry erase board I made several years ago for my wife. We never put it to use in the house so I put it in my shop. Below that is a rolling mechanics tool box. I store all of my wrenches, sockets, and tools of that nature in it.
You can also use Google image search to research a project. Unlike the PDF search, the image search provides a photo of what the project will look like, which is helpful in determining if you want to pursue building it. By doing an image search for how to build a step stool, you will have a ton of options that all lead to woodworking plans of various quality. (The how to part of these is important—otherwise you’ll just get pictures of step stools.)
