Cinnamon dough ornaments

[http://users.livejournal.com/_ciaoubella/]

This is probably incredibly stupid, but I want to make cinnamon dough ornaments before Christmas and am wondering how far in advance I can make them without losing all that cinnamon goodnessy smell before Christmas day? I know, I know, I could google it or call my Grandma, since I have HER recipe, but it's so early I don't think I can be a real person over the phone yet & I was already signed into lj...so, anyone have a clue?

Thanks in advance!!
