Wash the windows, hoover, dust, put some flowers in a vase, once the room is aired light a smelly candle, so you have a hint of nice smell.
I like a table cloth... Sorry, it's where I come from, Sunday is lunch with a white table cloth. I have a red one for Christmas and a yellow and lime green one for summer sunday lunches.
The rest is....pot luck! I tend to serve mezze type of food, cutlery in a big bunch given to children to set (haha), I jug of water with lemon, wine....everything is on the table, might be a cultural thing again, but I don't really clear the table for ages, for the people to be able to keep picking at stuff if they wish, bring a tray with a coffee pot and mugs. Children have dessert on a picnic rug in the middle of the room, leaving space for adults at the table.
I work by the principle: I'm hosting till you arrived, once you're at the table, feel at home. I am a feeder, not really a hostess, I like to enjoy my food and the company, catching up with people, the food is an excuse to gather round.
