In making our pad I leveled and compat6ed the area with our tractor and then layed 2-4 inches of number 2 gravel with no edging. I did not use any fabric, if weeds come up a little weed killer takes care of it. I've added a little gravel in spots over the years especially after heavy rainy seasons and the gravel settled some. Seven years and mostly maintainence free.
