I need some type of material to place around a chain link fence surrounding a new playground to keep the ground cover material inside of the fence. The fence builder initially left about 2" between the curbing and sidewalks because at that point I was leaning towards putting treated 2x8's around the perimeter. The distance between the line post varies from 6' to 9' and I was going to cut the 2x8's and attach them on center to each post. This however would hold up well but is going to require alot of cutting and be somewhat expensive. Do any of you have any other suggestions?
