Loving Mikayla Grace

But, I need some help. Is there an easier way to find 3-column blog templates with side bars on right and left, other than doing a Google search and spending my day sitting in front of the computer looking and looking. Also, is there a way to "save" my site the way it is now. Just in case I download a new template and don't like it, I can revert back to what I have now? If anyone can help me, that would be great. The hubby is a computer geek, but not a blog geek. He's got no clue what I should do.

** Please note that if you can help me, I'm not saying you're a blog geek. That just means you are AWESOME!
