Glue two styrofoam balls together using the hot glue.

Glue the two styrofoam balls into the base of the mini solo cup.

Fill a piping bag with approximately 1/4 cup of white caulk. Cut the tip from the bag and attach the 1M decorative tip.

Use the caulk to frost the top of the styrofoam ball like a cupcake.

Cut a 1″ length from a straw and place it into the frosting. Dust the top of the cup with festive sprinkles.

Glue a Starbucks logo to the front of the cup (optional). I printed off these mini logos using my printer at home (free downloadable file can be found at the bottom of this post – for personal use only).

Hot glue a loop of bakers twine to the cup for hanging. The best spot (so that the cup doesn’t tip too much) seems to be glueing the loop inside of the straw when the caulk is completely dry.
