Change the space between widgets?

Hi everyone,
I’ve already looked around in the forums for people with similar problems but none of it worked, seems like they had a different theme.
I’m using the Genesis theme over at http://www.sundaybelle.com/
and I can’t figure out where to change the space between the widgets? I want them to be closer together. If anyone has an idea, any help would be appreciated!

Thank you,
Angie
