Sagamore principal, Andy Larson, invited students and staff to show a little spirit by wearing their ugliest holiday sweaters on each Friday in December.
As the month went on, the sweaters got more ridiculous, creative, and hilarious.
Student DJs were selected to provide music during passing time, adding to the good cheer.
With their light-up sweaters glowing, Mr. Larson and assistant principal, Lisa Johnson, gathered the staff for a group photo last week.
