Create pegboard walls by running 1x3 strips horizontally at the top and bottom of the panel and every 16 in. or 24 in. between. Use 1/4-in. pegboard and attach it to the strips with washer-head screws. The strips will also allow you to mount screw-on hooks to the wall for very heavy items like bikes and wheelbarrows.

Extension Ladder Storage
An extension ladder is one of the most difficult things to store. When you need to use it, it has to be easy to get to. But there are long stretches when it just gets in the way of everything else in your garage. Here's a good solution: Mount it on your garage ceiling on sturdy racks made of scrap 2x4s that are screwed into the ceiling joists. Use two 3-1/2-in. screws at each joint to make the rack secure. These racks make it easy to slide the ladder out when you need it. Just make sure to position the racks where they won't interfere with your garage door.
