take a look on Boscoyo Studio's website and get a couple coro or ABS items. Candy canes, snowflakes, and more.. Ray Wu sells icicles pixels that fit boscoyo's icicles.. and a mega tree.. can start small with 10-12' trees Boscoyo has a kit. Falcon Controllers by far the easiest and most versatile.
**Note** ensure any pixels you buy have at least 4" spacing, 3" is a little cheaper, but dont fit all props available, (i learned the hard way)
