I LOVE the smell of cinnamin. I got lucky and acquired a small crock pot this year. I wish I had more, and not sure why I never bought one before hand. Well, it's great. I bought some cinnamin sticks, but made sure to get the craft ones, as they were much cheaper.
I made my own potpourri pot out of it. I filled it with water, added the cinnamin, some nutmeg, and some cloves. WOW, does my house smell great.
