adding space between containers

[Nyx1961]

My store is located at http://www.gardenofshadows.ca/. I would like to have a bigger space between the left column and the main container, where it says "Congratulations, blah blah" "Welcome Guest blah blah" and "Have you got yours yet? blah blah". I would think that I need to increase the left margin of the main container but I've looked over the style sheet and tried finding the code in Firefox with the Web Developer tool but I can't find where to change it. Any help would be appreciated. The theme I'm using is found at http://(sorry, site offline)/1-3-9d/...wist_of_nature. I really appreciate any help. Thanks.

Something like:

.centerColumn {margin-left:2em;}
