Glacial Age V2.0 Template

Would any of you be able to help with a query re this template.

The template is basically blue and down the left and right hand side of the Cart is a column in blue with a diagonal line across it giving a pattern.

We sell Tartan Items and would like to replace this "blue border" with a blue tartan border. I have a jpg picture of the Blue Tartan I want to use. What size of image should this be (my original is 1,000 pixels square) and exactly where in styslesheet.css do I need to change it.

THANK YOU.

Use the Firefox browser with the webdeveloper add-on which allows you to tinker with the stylesheet and see the effect immediately. It should help you a great deal in figuring out where to put the image you want to use. You'll have to save the changes separately and upload them to your site to make them permanent.
