Hi Ann,
This year my dh and I will be hosting our first open house, as well. We plan to do most of the refreshments ourselves. We have ordered buffalo wings from Sams. We plan on little smokies wrapped in bacon, decorated sugar cookies, cheese and turkey trays, pinwheel sandwiches, crackers, assorted nuts, M&M's etc. We will have a variety of drinks; wine, beer, egg nog, sodas, etc.
We will play continous Christmas music and may do caroling. I would love to hear your plans.
