These foam letters have been sitting in the back of my drawer forever. Here is a simple way to make an emoticon ornament. Just find the letters you need and stick them on. Could it be more simple? I was lucky that the letters came with parenthesis, but if yours doesn't you can cut it out from a letter C. Mine didn't come with a comma so I took the inside of the letter O and cut it into a comma. The period was the inside of the number 8.
I also spray painted my ornament because the paint was chipping off this really old ornament I found.
