Here is a simple way to add privacy (ok, a tiny bit) and some interest to a chain link fence. Simply rip cedar slats 1" X 1/4" and 4-5 ft in length depending on the height of your fence and 'slot' them into the chain link. The photo below is one example but you can double up the slats for more privacy (I could have added slats between the ones shown in the photo). Any, I think it beats the plastic inserts that are pretty common.
