Holiday Decoration - Dining/Party

I like to keep things simple with pretty details, practical solutions and decor which can be reused again. We have a large dining table,which can be extended, keep spare chairs scattered around the house, and nothing is too precious. Things can be moved around or hidden without too much effort. When we host party for more then 10 people we create a bar from a sideboard and shelves in living room, dining table becomes a buffet table, and put chairs into small groups around living and dining room. Fill the glasses, put music on, let the party begin...
