I want to be able to use Atahualpa to take a sticky post and have it span over the top of more than one column like this:

Can this be accomplished?

not sure what you mean, I don't see anything over multiple columns

Sorry, I changed it back to the Atahualpa theme.

Try this:

Well, it looks like I can use the add new widgets feature to make this work. I'll post my results when finished.

FYI donation made, this is my working theme now!
