Does anyone make their own yogurt?

4. I make it twice a month

A gallon of milk (whole makes it closer to greek) heated in a crockpot to 180 then cooled to 116. Add your choice of starters (I use one or two small containers of any decent greek yogurt), stir gently then cover and wrap the whole crockpot in a towel for 12 hours. Straining the whey is optional, I do usually, but with whole milk it seems to need straining less often. I strain in cheesecloth and it works great.
