Just wanted to say Thank You for this thread. This was one of the last items I needed to get my blog to look like my site.
My only problem is how links look when they wrap to a 2nd line due to the size of their title ... especially with post titles. [Which I just fixed by changing the width of each sidebar.]
main site: www.fibromyalgia411.info
Paula's suggestion about the left border under edit widgets did the trick, as I was still getting the default bar upon hovering over Recent Posts and Post Archives. That got rid of it.
