Changing spacing between certain widgets only

Wondering if it’s possible to change the spacing between two widgets in the sidebar of Twenty Twelve without changing the spacing of ALL the widgets?

I have an image widget at the top of my sidebar, and then a text widget. I’d like to bring the text closer to the image, but I’d like to keep the spacing of all the other widgets as-is. I figured this would be a pretty straightforward adjustment using CSS, but I can’t seem to figure it out (and I’m officially too frustrated to keep trying).

The website I am working on is http://www.rockstarpreemies.com

Thanks!!!
