The space behind a door is a storage spot that’s often overlooked. Build a set of shallow shelves and mount it to the wall behind your laundry room door. The materials are inexpensive. Measure the distance between the door hinge and the wall and subtract an inch. This is the maximum depth of the shelves. We used 1x4s for the sides, top and shelves. Screw the sides to the top. Then screw three 1×2 hanging strips to the sides: one top and bottom and one centered. Nail metal shelf standards to the sides. Complete the shelves by nailing a 1×2 trim piece to the sides and top. The 1×2 dresses up the shelf unit and keeps the shelves from falling off the shelf clips.
Plywood and long stock can also be a challenge to store in a shop. When I had an 8' bank of cabinets in my shop, I used to slide my sheet goods in behind it. Now that they are gone, I just stand them up against the wall and use a wedge system to keep them neat and upright. Long, narrow material goes on my lumber rack beside my table saw. I also store dry lumber standing on end in one corner of my bench room.
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.)
