At the end of the fabric for the seats, there will be plastic strips that get sewn to the material. You use the hog rings to punch a hole through the plastic and grabe the frame underneath the padding to hold the covers in place.
Like stated, if you do it yourself, when you take it apart, make your pattern a little bit smaller to account for the stretching to the original material. I found the easiest way was once I had one side attached to my center, to set the pieces over the foam and see where I needed to stitch the opposite side so that it would fit properly. There's nothing I hate more in an interior than seats with excessive fabric, or bunching in the stitching due to people rushing it and twisiting the fabric too fast. They stand out and just make it look half assed.
