Tips on colours are found on the seasons page. A good place to start is with the traditional Christmas colours. That is how we have organised the colour palette below. We are assuming this event will take place close to the Christmas date, so maybe encourage attendees to wear Christmas jumpers and partake in secret gift giving. All these thing will help set the atmosphere and mood, allowing you to keep decor fairly simple. A mini Christmas tree is perfect for these types of events, espespecially when it is not set in your home.
