I want to set up my doent on word into three column's for a brochure, how do i do this? steps please?

If you go to the Windows Office they have templates that are pre-made. For office 2007 click the Page Layout Tab ( Third tab)--.> Columns, and scroll down to 3. if you will be doing it fold up way, you can then flip it over ( make sure you insert it into the printer correctly) and you will be able to print on the backside too.
