If you think about it, many items you have in your shed likely come in rolls. Things like tape, garbage bags and twine are apt to get tangled if not properly stored. One of my favorite shed storage solutions is utilizing a paper towel holder for things a bit out of the ordinary. Hang up a roll holder to easily access garbage bags and keep them out of the way when they are not needed. Keep multiple rolls of tape on the rod to use when needed. It's as simple as that!
One solution is to screw a standing pallet into the wall of your shed. Now, you've created vertical storage to easily keep items off the ground.
