Here are some 3 column templates for New Blogger by Isnaini, examples of which can be seen at Wedding Tips (using the Nyoba 780 template) and Money and Finance (Using the Nyoba template). Note that the graphic header didn't come with the template and you will have to make your own graphic header and save it into your computer for later uploading. When you first load the template, your blog Header will just be a blank grey rectangle, waiting for you to add the graphic Header.
The templates can be downloaded from Free Templates. There are other templates available there, but they are old classic Blogger templates. To download the template, right-click on the "download" link and select "Save target as.." (wordings will be slightly different for different browsers), and then save it to a suitable folder in your computer.

To change your template to the newly downloaded template, in the Dashboard, click LAYOUT. You will see a Layout like the screenshot below (click to enlarge). Yours will be slightly because I have added various Page Elements. What I want you to note is the PICTURE Page Element in the Header. Click Edit, then browse to the graphic header you have saved in your computer, then click "Save Changes".
Update April 17 2007: I found the gray space in the header too deep for Wedding Tips. I thus went into the template editor and found this block of codes
#header {
height: 180px;
margin: 0px;
padding: 0px;
background-color: $headerBgColor;
and changed height: 180px; to height: 115px;
The codes thus became
#header {
height: 115px;
margin: 0px;
padding: 0px;
background-color: $headerBgColor;
The Header for that blog is as I want it now. Save valuable above the fold space.
