You'll find blocks like decorative lights and garlands, magically changing snow-topped stairs/slabs, decorative fences, doors, and mantels, Christmas trees that you can decorate, ugly sweater armor, foods, drinks, special interactable Candle holders for Hanukkah and Kwanzaa, and much, much more. The mod has a guide book with full descriptions of the blocks, items and their uses/recipes.
