Yup! I use a practice blog, too! I definitely don't have the best design ever, but I'm really proud of it, because I created it myself.
After searching endless tutorials, I learned one skill at a time. First, I worked on designing my own header (I use Paint.Net - it's pretty similar to Photoshop, but it's free!), then I moved on to creating 3 columns, my own background, and little other touches.
