This is a great way to keep all your bathroom accessories from sprawling all over the sink area.
A cedar panel serves as the backboard – I’ve found scrap wood just like this free behind the hardware store in their “scrap wood” bin.
The jars are fastened onto the backboard with hose clamps, like these from Powertec. Make sure you measure the diameter of the mason jars you’re planning to use before buying the hose clamps.
According to wikipedia, these are the diameters of the 2 most common mason jar sizes.
Regular mouth, external diameter: 2 3/4 inches
Wide mouth, external diameter: 3 3/8 inches
