I've enjoyed seeing which new templates people are choosing, and the ways they set them up. I would like to have 3 columns like many do, but I can't figure a way to get my large photos centered. I just don't think it works.
Jacqueline from Purple Chocolat Home, asked me to come tell her how I adjusted the width of my blog. I figured others may not have found where to do it yet, either, so I will let you know. If you have discovered any tricks or tips, please leave a comment, and if you want, a link to your blog in the comment to fill us in on what all fun things we can do.
What I did do, was go into "layout" and saw that you could adjust the width. It's in the second column, after, "Body Layout" and "Footer Layout". I drug the little arrow for the entire blog clear to the right, to make it the widest I could, then adjusted the right sidebar until the photos on both sides were pretty much centered. My numbers ended up being 1,000 and 230 px.
I just went to Jacqueline's blog, and saw that she is not using a Blogger template, so I don't know if this will be helpful. Jacqueline, maybe you can use the numbers of px to find a way to adjust yours.
