Making Homemade Vanilla: Or, What to do with a gallon of vodka

I was so inspired by this post over a the Heavenly Homemaker's blog that, after I stopped rolling on the floor laughing, I ran out and bought a gallon of vodka!  Oh, and a bunch of vanilla beans.  I had never considered how the extracts we use every day were made, and I was amazed at how simple it was.
After cleaning the gallon jar I just received in my Azure Standard drop this morning, I took the vanilla beans I purchase at Olive Nation and cut them down the middle almost to the end and tossed them in the jar.  When I was finished with the beans, I just filled the jar up to the top with vodka, and after taking a picture, tucked it into a dark corner of my pantry.  According to the Heavenly Homemaker, all I have to do from this point is shake it up every once in a while, and just before Christmas I'll have enough vanilla to share :).  If it comes out as well as I hope, I will wash the jar out and fill it back up!
