All yogurts need a starter and instead of buying a powdered starter, all you need is a small 200g pot of natural yogurt as your starter (just make sure that it says that it has "live cultures" in it). You can continue to take one and a half tablespoons from this pot and can get at least 6-7 lots of yogurt from one small pot. Then, all you need is a thermos or a jar and some time to create it-no special container or anything that you wouldn't already have in the house. All you do once you mix and heat the three ingredients together is to leave it for 24 hours and you end up with yogurt! The powdered milk is to give the yogurt a bit of body to it and I used an organic full cream milk (low fat milk is also ok but non fat is a challenge) and you can also use organic yogurt as your starter.
