There are two things I love in this world: blankets and pillows. Put yourself under a blanket and over a pillow and you're set for life.
Of course, there is the question of where to store all your blankets and pillows. Any old shelter would do, but if you are going to get cozy, you might as well go all out. Any one of the following places would do nicely. I think I'll move into one. That is if I can ever bring myself to leave this very cozy bed.
