Caulk Tube Nest
Before I made this caulk nest for my shop, the tubes rolled all over the shelves like slippery logs. To build one, cut 10-in.-long pieces of 2-in. PVC pipe and glue them side to side with PVC cement. To get straight glue lines, use the print along the side of the pipe as a guide. As you glue, hold the pieces together for 60 seconds with hand pressure or a clamp until the glue sets. Be sure to apply the glue only in a well-ventilated area. Glue on one tube at a time to fit the available space. That's it— your caulk tubes are now organized.

A PVC pipe connected to a vacuum hose lets you reach up to high spots or into narrow crannies, so you can suck up those cobwebs around skylights or exterminate dust bunnies behind radiators. A 10-ft. piece of PVC pipe is inexpensive. Here's another vacuum attachment hack.
In the plumbing aisle, you'll also find PVC and rubber 'reducer' couplings that let you connect your vacuum hose to a different-size pipe.

Fill a sturdy cardboard box with sawed-off shipping tubes or scraps of larger PVC pipe. Then use it to store and organize all those short pieces of molding, pipe and dowels.
