A perfect gift for a Memorial or Independence Day host, these patriotic tumblers are created using a process similar to eglomise -- the 18th-century French technique of painting directly on the reverse side of glass.

For this project, Martha uses special, nontoxic, dishwasher- and microwave-safe paint pens, which create an effect that is rich and colorful yet translucent. When downloading our star template, keep in mind that it is designed to fit a 4 3/4-inch-tall glass but can be centered in any glass you like; alternately, you can enlarge or reduce the image, using a photocopy machine.
Red and blue paint pens
Download and print the star template. Center it inside the glass, and affix it to the glass with tape. Using the red and blue pens, start filling in the spaces of the star with dots (you can use different sizes and place them as randomly as you like). Let the paint dry for 24 hours.
After the glasses have dried, place them into a cold oven. Turn the oven on to 325 degrees, and bake the glasses for 40 minutes. Turn the oven off, and let glasses cool, leaving the door ajar. Now the paint is set, and the glasses can be washed in the dishwasher.
