This was hard to get a good picture of. What I did was E6000 glue the mugs together with a bud vase base.
The bottom of the cups had a star in the pattern, so I turned one on it's side and glued it to the top to look like a star on top of the tree and you can put a tea light in the cup to light it. These cups were $0.25 each at my pole building sale - no one bought any of them. I have another project to do with the rest - I will post later.
This will be available at the "Vintage & Handmade Christmas" Pop Up sale here at the farm on December 12, 2014.
