How to arrange blogs on Blogger
In order to change or rearrange the way your blogs are viewed on your Blogger page is fairly easy. All you have to do is log into your Blogger account, then go to your dashboard. In the section, where it says, "Manage your blogs," select the 'Layout' button on the blog you wish to change. Once you are on the Edit Layout page, select the 'Edit' button located in the 'Blog Archive' box. This will open up a small window where you can change the hierarchy of your blogs. Not much of a selection however, in the ways you can have your blogs posted. You only have the choice of showing your older or new blogs first, then the rest follow suit.
I hope this information was helpful to you, as well as any future Blogger users.
