Liz Kalloch and Maya Stein from Toad Hall Editions will be showcasing work at Waterfall Arts Holiday Pop Up Market, an indoor Maine-made artisan market. Friday evening will be extra merry with refreshments and a bonfire in the front yard. Stroll the building to look into the public-access studios (clay, print, glass) and other studio artists selling their wares. Young artists from the after-school art programs at Waterfall Arts will be in the Bridge Studio creating one-of-a-kind, handmade potato stamp wrapping paper for your purchases.
