The travel mug comes with a piece of paper that they can color to place in the mug, I used this as a template for designing my own instead. On one side I did a glitter handprint by tracing my son's hand and filling in the area with glue. Then, I just sprinkled glitter over the glue area.
On the other side, I placed a picture of my son along with the year and his name. I love the way it turned out and it is now my Christmas present from him.
