Once you get your shop organized, you’ll fully realize just how nice it is to be able to find and access things easily as well as have room to work! You'll soon find yourself actually putting tools back where they belong when you are done with them. Whether the shop is where you spend weekdays or weekends, you’ll really appreciate an organized shop.
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.)
