I agree with Davemil,buy some new camo.Of coarse,if you want,you can sit down with some magic markers and "re-color" your camo.
Sorry,I forgot,you would have to buy the magic markers,so I guess thats out of the question.
All kidding aside,if you stay away from natural fibers in your better($,high-end camo),the better off you are.Natural fabrics WILL fade,where as synthetics are LESS apted to fade,and the servicability is much greater.
If you keep this simple rule in mind,your camo and wallet will stay intact a lot longer...Bob
