When I built the cabinet that houses my marking and mea­suring tools, I wanted to make sure each tool had its own spot and would stay fixed. I cut the drawer bottoms and used contact cement to adhere ¼" cork sheet to one side. Using an X-acto knife, I cut around each tool, then peeled the cork off the plywood with a chisel. I made the handles with hand planes, cut them to length and glued them to the fronts using a rubbed hot hide glue joint.
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.)
