If you haven’t worked it out for yourself yet, here are some step by step instructions on Howto: Change the look of your blog.
You will learn to:
- Change the theme– choose from a large number of preset themes that can totally change the feel of your blog
- Add a header picture– choose one of your own pictures to remain at the top of your blog at all times
- Work with widgets– your list of links is a widget, as is your calendar and you list of pages. These can all be moved around on the side of your page, or swapped for other more interesting widgets!
There are many different types of widgets. To learn more about what they do, visit the FAQ page at WordPress.com
