Last season I converted my entire backyard into a flower garden. One of the things I did was to edge the garden with plastic edging. It looked fine. This year I decided to pretty it up a little. So I dug up the dirt between the plastic edging and the driveway. I needed about 2 inches of space so that the pretty scalloped concrete edging stones would fit. After I had dug out the dirt I was able to place the edging stones into place. What a difference it made! Looks so much nicer!
