Using the ¼ inch painters’ tape, create lines going around the jar. This should leave various shapes and patterns visible with tape outlines.
With whatever desired color, paint the jar using a paint pen. Tip: for a more variated look, make sure no one color shares a border with a shape of the same color. Any type of acrylic paint would also be useful for this step; I just find pens easier to maneuver on the glass.
Let dry and repeat above step until the paint is opaque and without streaks.
Remove tape gently, scrape off any excess paint on the jar being careful not to scratch the desired paint.
Using a black paint pen, create outlines around each shape.
Cover the jar in the acrylic sealing coating, make sure to do this in a ventilated area. Let dry.
