Customizing your blog can be fun. Take it from me, I have probably switched between themes more often then I have written blog posts.

Here is a quick overview of how I achieve the current look using the new WordPress default theme TwentyTen.

Step 1

Enable Custom CSS. Go to Dashboard → Posts → Plugins and active Simpler CSS 0.5

This will give you access to Dashboard → Appearance → Custom CSS

Step 2

Copy and Paste the following CSS in to your Custom CSS.

#site-description{width:300px;}
#site-title { width:640px;}
#branding img{ display:none; }
#access{ margin:-85px auto 10px; background:none; }
#access .menu-header ul, div.menu ul{ float:right; }
#wrapper{ margin:20px 0 0 10px; border-right:10px solid #D9D8C4; }

#content, #content input, #content textarea {
 font-size:12px;
 line-height:18px;
 font-family:"Lucida Grande","Lucida Sans Unicode",sans-serif;
}
#access ul li.current_page_item  a{ background:#333;}

Step 3

Go ahead and change the background color to #EEECD6
You can do that under Dashboard → Appearance → Background
