This was a super easy, fun project that I knocked out in a couple of hours with materials I had in the house. I started with a scrap piece of 1/4 inch plywood but you could certainly use something thicker. I drew out my design with a pencil (and did a lot of erasing) until it looked suitably like a cup. I wanted something that looked like it might have been found in a thrift shop so perfection was not the goal.
Using jigsaw, I cut out the cup shape and lightly sanded the edges. I drew over the pencil marks with a marker knowing it would show through a light coat of the white paint. After a quick white wash, I added some "coffee" and shading using a beige paint. Finally, I used a gold sharpie to retrace the faint marks to make the final markings on the cup. Done!
