What great memories you have made with your Grands (and the fake one!) by making this an annual event.
Years ago a couple of girlfriends and I did it with their kids for a few years .... whole villages would get made! Each year they got more elaborate with everyone watching for great add-ons of cookies, pretzels, candies, cereal, etc that'd be just "perfect"!!! I didn't have kids ... but I sure had fun with them and have the memories too!!
