The templates that you've downloaded have been designed to open in Adobe Photoshop and other widely accepted graphic design programs. You'll need to open the template files and start importing existing artwork or creating the art right in the template. Doing this will ensure that everything will line up right from the start. Please note: Once you've open the template at 300 dpi and in CMYK, do not make any changes to the template itself. Doing so could mean we have to reformat your work, and there may be additional graphic charges.
