The University of Maine at Farmington's December craft fair, held at the Olsen Student Center on the UMF campus and run by the university's Conferences and Events office. It takes place on Chester Greenwood Day, the town of Farmington's winter celebration of the local inventor of the earmuff, and is the second of UMF's two seasonal craft fairs — the first is held in November. Crafters apply directly to the Conferences and Events office; a raffle runs alongside the fair, and food vendors need a Maine Mobile Vendor License.
