We use mil-spec 1" pals webbing spaced 1.5" apart using bar tack stitches over a 2" wide laminated hook and loop platform. simply roll out bartact molle strips over your desired area and cut to length.
Then, just burn the end of the webbing to keep it from fraying over time.
Attach to seat, and you are done with that row...move on to the next strip, and line up to the bottom of the row above (or top of the row below). a 1" gap between rows of pals webbing will automatically be created due to the extra 1" at the top to make your system multi-row molle compatible!
Add as many rows of bartact molle strips as you want (or can fit!) and trim them to whatever length you'd like, in order to conform to the area you are covering. you can create a panel to cover an entire hook/carpeted area, or just a partial area the size of your choosing. you can even make angled cuts to form around seat latches and child seat safety latch locations.
