Update: I've adjusted the width of the three columns using these instructions provided by Three Column Blogger. This change was even easier to do that the first change. I also learned how to change the width of each column to whatever I want it to be. No more problem with "picture widgets" that are too wide for the sidebar!
I'm almost done with my new 2009 look. I love having three columns to my blog - makes it so much easier to arrange things on two sidebars instead of one. I did this with the assistance of Three Column Blogger - it was easy and fast to do. I have no idea why I waited 4 months to do this! If you'd like to do this to your Blogger/Blogspot blog I recommend you take a look at Three Column Blogger. Just click the name of your Blogger template on the sidebar and you will be taken to the page with directions for your particular style of blog.
Now I need to follow the directions for adding margins so everything isn't so squished together on my blog! Hopefully I can do that tomorrow. I'm not connected to a printer right now, and I find it easier to have both the printed directions in front of me as well as the screen directions (where I can copy a specific code if need be and not have to retype it!)
Thank you Three Column Blogger, whoever you are!
