Before you begin, you want to make sure that you've cleaned your coffee cup lid; wash it with a little soap and warm water to remove any coffee residue, and allow to dry. Once it's clean and ready, you're going to make sure you can hang your ornament! Cut a piece of ribbon, yarn, or string several inches long. Make sure that it is not too thick to fit through the "sipping hole" of the coffee lid.

Tie your ribbon's ends together in a knot so that it forms a loop, as shown.

Push the looped end of the ribbon through the sipping hole in the lid.

Thread the knotted end of the ribbon through the loop and pull through.

Gently tug your ribbon tight; it's now secured to the hole in the lid, and also gives you a way to hang your ornament!

Using your lid as a guide, cut out your construction, scrapbooking, or wrapping paper into a circle that will fit on the inside of your lid. Trace the circle with your marker and cut it out with your scissors.

With your hot glue gun (and an adult to help!) glue the paper into the inside of your lid as a base. From there, you can cut out and glue in a photo if you wish!

Further decorate your ornament with stickers, pretty trim, jewels -- anything you happen to have!

You don't have to stop there! Here, I'm decorating the back of the lid (the outside of the lid) by cutting out a snowflake...

... and covering it with glued-on beads!

Here's a look at my finished ornament backing.

And here's the front, with all our silly faces ready to decorate the tree!
