Some of these patterns were created using Delphy's Pattern maker (
http://www.modthesims.info/download.php?t=342998). They should be installed using Helper Monkey available at
http://www.modthesims.info/download.php?t=344611 . After installing Helper Monkey and downloading the desired pattern, just double click on the file to install. PLEASE NOTE - You CANNOT have The Sims running when you intall a pattern or it will not work!
