Wordpress Themes - WP Forum at BFA - [SOLVED] Float Image Between Center Column And Footer

I'm trying to float the logo in the lower corner so that it cleanly breaks into the bottom border:

Similar to how the menu buttons are cut into the border.

I know I can achieve this with an image for the border but I'd prefer to use CSS if possible. The image is currently as a background in the footer. If I move it up using -10% y position, it won't go up past the footer boundary. Similarly, if I use the Center Column background and place it at 110% y position, it disappears behind the footer space.

Is there a way to actually float the image above that? Here's my current code in the footer:

HTML Code:

background:url('http://www.labohemeevents.com/wp-content/uploads/2011/08/lblogo-e1312917727161.jpg') 2% -10% no-repeat;

Thanks!
