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.
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.
Woodworkers are a social bunch, and there are a few popular forums where people share thoughts on tools, discuss technique at length, and—of course—upload their plans. Some of the most active online woodworking communities include Lumberjocks, Woodworking Talk, Wood Magazine, WoodNet, Kreg, and Sawmill Creek. Search those to see if they have what you’re looking for (either with their built-in search tool or with Google’s site-specific search, e.g. site:lumberjocks.com side table).
