Put on your jeans and sit down in a chair. While seated, rub 60 or 80 grit sandpaper over the seams, knees and any high areas of your jeans where the fabric is creased. Sand the belt loops and edges of the pockets as well since these are places where natural wear occurs.

Mark any areas where you want to place holes or fray the fabric with chalk while you are still wearing the pants. The knees and thighs are the most natural places for this type of distressing.

Remove your pants and place a wooden block inside the pant leg under the area you marked to create a work surface. For a threadbare look, rub the pants perpendicularly with a pumice stone or rasp. If you prefer a hole, use scissors or a knife to cut the fabric and then rub the edges of the cut to create a frayed edge.

Spread your jeans on an old towel or sheet in your garage or other safe work area and pull on a pair of rubber gloves.

Wet a sponge with bleach, ring out the excess, and run the sponge up and down the pant legs. On areas that you want to appear more faded, such as the knees, rub harder to apply a bit more bleach. Do the front of your pants first and then flip them over and repeat the process on the back.

Wash your jeans by themselves in cold water for a full cycle. Dry your pants on low heat or line dry.
