Homemade Yogurt

I had yogurt working in the crock pot and Shawn's raw veggie burgers working in the dehydrator.  I was excited about the yogurt, but it didn't turn out like yogurt.  It was thin and runny even after draining for 24 hours.  I think 1. the house was too cold and 2. I should have used cheese cloth, not a paper towel to drain.  However, it did make a really good crème fraîche to use for chicken paprikash and in chili and other such applications.
