For this project I used a hammer, wire cutters, needle-nose pliers, a picture hanging kit that had nails and wire in it, and a piece of scrap wood that I found in Home Depot. Instead of the wire and nails, you could use metal pipe clamps and screws by drilling a hole through the pipe clamp and simply screwing it into the wood. The pipe clamps are adjustable so that they fit snugly around the mason jars.
Step 2: Step 2: Measure and Hammer in Nails
For this step, you just decide how many mason jars you want to use and then measure out where you want them to be placed on the piece of wood. I found the middle and then the halves of the two side sections and then went about an inch on either side of the jars' measurements. I then nailed in the holes and wrapped the wire around the nails making sure not to make them too short or too long.
Step 3: Step 3: Insert Jars & Fill Them with Stuff
This is the best step because you just insert the jars into their wire holsters and fill them with whatever you want. I like that the jars are removable for cleaning and re-stocking.
