Hello all,
I'm trying to figure out if it possible to have a 3 column widget row followed by a two column row below it with the blog posts on the left and your regular side bar widgets on the right.

Can someone please help me with the code? I've got the 3 column code figured out but can't bring it back to 2 columns afterwards.
