What do you like to do with your stems?

My buddy and I have a ton of stems collected from a year or two and its about time to do something with them. I was thinking about putting them into ISO alcohol to make some "hash". I've seen people put them in tea and I suppose I could do that after I make my hash, but what do you guys like to do with stems?

I saw someone post a pic of kief made from stems. Is that even a good idea? I feel you would just get a headache from smoking wood. Any suggestions? :)
