Making Yogurt

My friend Erin called this morning while we were making yogurt. She asked me to post a picture tutorial on my blog. I figure, since there are already many really good one's out there, I would just link to one of those. Here is my favorite. I pretty much make it the same way she does. :o) Please post a comment if you make your own - I'd love to know what you use (kind of milk and starter - we use Horizon's organic whole milk and Stoneyfield plain for starter), how you do it and how you use the yogurt (ours goes in smoothies, mostly).
