In conclusion...

There are many blog sites available. Not all sites are free. Some will give you a free trial and then charge you a small monthly fee. We suggest trying out a free site at first. If you find a site you like better you can always move your blog there.  We are listing a few free and a few pay sites. You can also look through other peoples' blogs to get a feel for what you want your blog to look like.
