Centerin content on page

hi, I have searched forums until my eyes have crossed, but im afraid I dont know nearly enough about wordpress for any of it to make sense. I absolutely love this theme, but I would like the content on my page to be down the center and I’m not sure how to do that. It seems that its reserving space for the sidebar even though Im not using any widgets in it. But I really have no clue. Here’s a link to one of my pages, although it’s a site wide thign that I would like to fix.

Hi,

Use the Full Width page template for each page you’d like to change. When you edit a page you’ll see the Page Templates menu on the right side.
