Recycle a jar into a pretty gift vase or pencil pot that will add some color to the recipient's desk.
To make the paints stick to the glass, first mix the colors with some glue. Keep the paint thick so it won't run.
Use brushes or cotton swabs to paint a design on the jar. To erase a mistake, use a paper towel to wipe off the paint before it hardens.
Let the paint dry, then seal the finished design with a coat of glaze.
