@Goodywood - You don't have to bundle all the patterns and left-out items together, but putting the patterns in first should prevent the problems that many have of them NOT exporting when uploading. Some of these pattern files tend to break uploads, especially the tiki patterns and variegated vase. Homes that are decorated with these patterns sometimes just refuse to upload until the pattern or item is replaced with something else. So, putting an item with the unique pattern in it before installing the set itself helps.
