A Costume for National Flossing Day

It's that special time - National Flossing Day Eve!
Time to plan your activities for tomorrow.
Here's one possible plan:

Print this Smiley Face Mask (If it won't print 8.5x11, email for a full sized pdf)
Insert floss at the corners of the mouth, and use it to entertain friends and family.

It certainly would look great on a chorus line of flossers in your version of the National Flossing Day Video Challenge!
