Christmas in the Valley, a juried holiday show featuring hand-crafted items, will celebrate its 20th anniversary this weekend at the Foster Country Club. The show’s origins involved three women artists from Foster who took turns hosting small gatherings of friends in their homes for holiday shopping, before moving to larger venues. Returning vendors include Glocester Greens & Goats with goat milk lotions and soaps, Unique Batik’s hand-dyed silk scarves, and RI Handspun’s creations. Other offerings include jewelry and wine.
