Sometimes I decorate a little for Halloween, however, when it comes to the Holiday season I like to decorate more with the Holiday themed items! I love having Illuminated trees near the entrance. I do have two reindeers at the entrance of one of my islands all year round!
I do plan on making an area above my town hall for that exact reason, I wanted an area I could change even after fully finishing my theme so I won't be too bored.
I don't have too many ideas for it yet, mainly fairground, holiday seasons. Maybe a modern thanksgiving Park?
I put Halloween and Christmas decorations around my island every year. I also change the bushes at the very front of my island to seasonally blooming ones, and change the display of clothes outside Able Sisters to ones that match the month
I tried to decorate a certain area on my new island for each of the major holidays I celebrate, but it was a bit too hard to keep up with, especially given that I go through phases of playing a lot, and not playing at all!
I try to a bit, like with thanks giving and Christmas since it’s nostalgic for me, but I only do a little and when I’m actively playing which isn’t recently.
When I put up a decoration, it’s permanent, whether it’s seasonal-themed or not. I hardly change my designs. I go with what designs I like most (which includes a Halloween-themed room all year long).
