1. Brighten up the house with candles and lots of fairy lights (bought secondhand or borrowed from friends), but make sure your ancient electrics can handle all the lights being turned on at once.
2. Solar powered outside lights are great for decorating the front of the house unless the sun hardly comes out because it has rained all week and the batteries run out of power before the party has started. I had to charge them up inside.
3. Make a note of what food people bring so that you can thank them when you eat it later. I have no idea who made the little caramel tarts but they were delicious.
