I don't know about you, but I never have enough space. I have shelves, but I always have bits and bobs that I wish to put on them other than spray cans. When spray cans are stored on shelves it always seems that the one you want is in the very back. This rack puts them all out where you know what you have and you can simply reach out and get the one you want.
Step 1: Getting the tools you will need
a pair of pliers that have wire cutters built in,
a screw driver with the sort of tip as the screws that you choose to use,
I prefer the locking needle nose type pliers with the wire cutter at the base of the jaws when bending and cutting wire, but regular pliers will work fine.
For the saw, a cross cut saw will probably be the best unless you have access to a power saw.
For the screw driver, choose one that has a good tip that securely fits the screw type that you have chosen. Phillips or cross head screws that do not require pre-drilling will probably work best for this instructable.
