I find the best way to get good results when distressing is to start with a really really good paint. Let the paint dry thoroughly and then add a second coat. This base coat is the one you will want to have peak through the other colors. You will be sanding, scuffing and rubbing off the other colors, but you want this one to stay.
Once the base coat has dried, you will apply the main color with a dry brush. I used a nasty old brush that was hard as a rock. It doesn't really matter as long as it will put paint on unevenly. So if you are using a nice brush make sure to only put small amounts of paint on and even brush it back and forth on a paper towel to get off any excess paint. Then, start applying the paint until you have enough of the base coat peeking through to go for the style you want. I usually add some brown paint to my main color, but don't mix it in (see the above picture) so that the paint looks aged. I also use my finger to swipe paint unevenly on the sides. After I'm satisfied with the coverage, I like to add some definition to the edges and indentations on the frame by adding some brown paint mixed with a glaze medium.
