21. Storage Corral
Use scrap wood to create an upright storage corral, and create separate compartments with plywood slats. This takes up a lot less space than having all of those tools and sports equipment hung on the wall. Get more details about this project here.
22. DIY Wooden Shovel Rack
Up, up and out of the way! A wooden shovel rack is strong and sturdy for those heavier yard tools. With this design you can fit several yard tools in one slot. Go check out the instructions over at Family Handyman.
23. Repurposed Hanging Shoe Rack
I used to have one of these attached to the back of my closet door for storing shoes, but the little compartments are so perfect for the garage! You could use it to store your garden/dirty shoes, cords, and other miscellaneous items that tend to get lost in the clutter.
