Thank you to The Background Fairy. While I was at over at The Knitting Contessa and admiring her site, I discovered that I, too, could have a pretty background on my blog just by going over to The Background Fairy's site. She has samples with the instructions and code that you just copy and paste into the html of your Blogger blog.
The button for the her site didn't come through, but I'm working on that. Until then, you can use the link in the post to check her out.
