To do this yourself you will need: some nail varnish, a cocktail stick, an erasable whiteboard pen, ruler and the jar.
1. I first removed the wax and cleaned the jar.
Here is a link on snap guide on how you can do it:
2. Draw vertical lines using an erasable whiteboard pen to use as a guide. When drawing the guide lines make sure there are an even number of sections otherwise the design will not flow.
3. Then use the cocktail stick to draw the design on with the nail polish. I just dipped the stick into the pot.
