I've got a Eurocuisine yogurt maker. Instead of one container to ferment in, it has 7 little 6-oz glass jars with lids. I've got an extra set of jars so I can make 2 batches back to back and be good to go for 2 weeks (or 1 week if I let my hubby have some)!

I hadn't read about that thermos idea. I have read that you can use a heating pad. There sure are some interesting, innovative ways to make yogurt.
