Paper or something similar to protect your surface while you are painting.
Instructions
Lay your paper down to protect your surface. Squirt a bit of paint onto the paper.
Apply the paint uniformly to the jars. I started on the bottom and using long even strokes, brushed toward the top. Then I went around the jar threading.
The chalk paint covers well so it didn't matter that one of my jars had been previously painted.
When your jars are painted, set them aside to dry. Chalk paint doesn't take long at all.
Next, spray your jar lids and rings. If you don't know how to spray paint watch a youtube video. I know how but I'm not very good at it so no judging! HA!
After all your paint has dried, assemble your jars and rings. You can also take some fine grain sandpaper and rough up the edges to give the jars a more rustic worn look.
