I discovered this calendar via Design Related (thanks for the photo!) and thought it was such a fun idea.
It features people wearing clothing according to the weather/season/holiday for each month, as well as being divided into the northern and southern hemispheres.
Now, I'm also thinking this could be a fun little craft project. Yes! I love a good project. You could certainly get creative with this. Plus, you'll have the added benefit of being more organized, or at least on schedule.
Ah well, time for lunch and some thinking about my apt situation.
