I have copied the Garland theme we were using to garlandsimulistics in the customisation directory /simulistics.com/drupal/sites/all/themes/.
At present I am confused that style.css isn't being used though print.css is. A css file with a number of lots of digits is used. It may be a processed version of style.css. I'll investigate futher.

-----------------
If the Garland colours are changed the modified css are copied in to the files dir and used from there. Those css are the ones to edit, e.g. "/drupal/files/color/garlandsimulistics-4d3e4149/style.css";
I've shrunk the margins to 160px.
