Some ARF manufacturers provide extra covering in the same color as that that is at the hinge line. You usually have to cut it into strips wide enough to crease it down the middle and fit into the bevel of the hinge line. Iron it to both sides of the bevel. You only need to apply it to the top side or the bottom side. Top or bottom is at your preference. The top side may look better, since it hides the hinges. It depends on how neat and accurate your are at applying it. Sometimes this will not hold well either, and come loose with time. Often there is a place where it does not fit well with the gap and hinges, and the crease is not straight, then somewhere in its range of motion it gives an irritating popping or crackling noise. There needs to be a straight line in the crease.

Many people get a clear tape that sometimes is sold as a hinge tape. Probably the most flexible (no crackle) and easiest to apply is 3M Blenderm. This I understand is what is repackage and sold in hobby shops as hinge tape. Another possible tape to use is Scotch MultiTask. It, or the Blenderm may, or may not, be found in your local Ace Hardware or an Office Depot. The Blenderm can also be found in a medical supply store, as it is used to apply things to skin.
