Candy Cane Wall

The wall can only be made while the Christmas season is running, because the blocks it comes from are seasonal too. Anything you craft or place during that window stays in the world afterward, so nothing you built disappears in January. What you lose is the ability to add to it. The usual habit is to make far more than the build needs in December and stash the surplus, because coming back in March to finish one more row is not an option.

Red and white stripes are loud, and a room fully papered in them fights with everything you put in front of it. It works better as trim: a band behind a shopfront, a stripe under a roofline, or the back panel of a single gift themed room. There is a green version if you want two tones without touching paint.
