You will need:
A bottle of old nail polish (that you do not use anymore)
Nail polish remover
Paper towels
Scissors
Step #1:
Take a bottle of nail polish that you no longer use. (I am using this bottle of white nail polish that is too thick and chunky to use anymore.) Take the cap/brush off and wipe the excess nail polish off with a paper towel. Before it starts to dry, clean the bristles carefully with nail polish remover. I like to fill the cap of the NPR with it and soak the brush for a few seconds, swirl it around until the color comes out. 

Wipe the brush clean with a paper towel or cotton ball to dry. Note: all nail polish brushes are different! If you clean the brush off too roughly, you could easily pull the bristles out! So be careful if this is your first time; the brushes are sometimes very fragile.
Step #2:
Using your fingers, carefully split the bristles into two sections: a section that you want to keep, and a section that you are going to remove. I have split off roughly 15-20 bristles here that I want to keep. The less bristles you have, the thinner the stripes will be.

Step #3:
Use scissors to carefully cut off the sectioned you have decided to remove. Cut as close to the base of the brush as possible. If you are afraid to cut off too much, I would say just cut off half the bristles; you can always remove more later.

Step #4:
Test out your new custom made striping brush!! I drop a few dots of nail polish on a piece of paper and dip my brush in it to apply.
This is a really great way to make use of your retired nail polish, especially if you (like myself) have a problem throwing things away. Also, you can make them as thick or as thin as you want so you have just the right striping brush for you. You don't have to be a slave to the nail art polishes anymore. Hope this helps, and thanks for following!

The lighter green on the tips is from my new stash, its "Big Money Frost" by NYC, underneath it is "Carribean Frost" by Wet N Wild. I did a layered asymetrical tip with black stripes coming from one corner. I'm going to call that kind of a design a "burst" until I can figure out another word that describes it. Anyways, I made the bursts black with my striping brush and on a few of them I painted a light coat of glitter just on top of the burst and coming out on to the ends of the stripes. It looked really cool in the sunlight, but not sure if you can see it in the pictures.
