Apply your heart and burnish the edges well to avoid paint leaking under your masking.
Paint your entire jar and the outer part of your inner jar. You may need 2 coats.
Let your jars dry completely, then remove your heart mask. You might need to cut the paint around the edge of the mask with a craft knife first.
