YAY FOR CONTEST. It took longer than I expected to set up, but I'm glad it's up!

As for your question, Christmas would be during winter in the comic- so that's why! That said, you don't need snow and whatnot! I say winter theme mostly since it covers Christmas, New Years, and other holidays. I was originally going to make it Christmas themed, but I wanted to broaden the theme a bit so people can do whatever. As long as it's clear that there is some sort of holiday/winter theme going on, anything goes!
