5. Pendant lights shaped as stars hangs in almost every window, or in ceilings. If you must use ceiling or floor lighting, make sure the bulbs are exterminating warm light. Fluorescent light is forbidden all year round, but even punishable over Christmas.
4. Natural materials. Bring the outdoors inside with wood, moss, evergreens, pinecones, and other natural materials. Gather a tree branch and hang string lights. Stay away from glitter and plastic decor. Think neutral.
