As your interest in woodworking grows, you’ll want to subscribe to a woodworking magazine. This will help feed your new found obsession with articles on tools, techniques, and woodworking plans. As a print magazine subscriber you’ll also gain access to their database of plans on their websites. Popular magazines include, Woodworkers Journal, Fine Woodworking, and Popular Woodworking.
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.)
