Tool Wall: Trace tools with pencil, then remove tools and use a sharpie or paint for bolder lines. Could also keep post it notes nearby to put on empty spot when tool is loaned out, so you can note who borrowed what & when.
The Family Handyman DIY Tip of the Day: Movable Bike Rack. Cut four 3-1/2 in. blocks, stack two on top of each other, and screw them together. Now screw them on the end of a 4-ft. 2x4 and repeat the process for the other side. Then screw in the bicycle hooks. Lay the rack across the garage ceiling joists, and hang your bike from the hooks. When you need to get behind the bike, simply slide the rack out of the way.
