'Tis the season, as they say. Thanksgiving is around the corner and just a little further down the road we hit the holiday season. The festive spirit is already growing and you've likely seen that reflected in the windows of a growing number of business is Ann Arbor, Washtenaw County and parts of southeast Michigan. Much of what you see is the work of a group of local artists that call themselves, the Novemberistas.

In this week's edition of WEMU's "creative:impact," Mary shares the story of the Novemberistas, and more.
