Editing Terra Firma theme

[saint]

Greetings,

I am attempting to edit the Terra Firma theme. I want to remove the right hand sidebar and use the entire space for content.

I have accessed the theme editor and removed the sidebar div / component.

<div id="sidebar">
<?php get_component('sidebar'); ?>
</div>

This removes the sidebar - but there is still a blank spot where the sidebar used to be.

I tried looking for a width variable to adjust- so that I can remove the blank spot - but no such bird exists.

Any suggestions ?

Thanks
