It is so easy to make yogurt that it isn't even funny. Get some acidophilus yogurt at the store, or buy the packets for making yogurt. (You will never have to buy them again.) Put a glass or jar of milk on the counter with 1 tbsp of the acidophilus yogurt in it (either that you made or bought). Within 24 hours you have yogurt. Once it gets thick, pop it in the fridge. Just keep using the yogurt you have to make new yogurt the same way.
