It is good to invest in good branded brushes and tools, but for beginners and not very avid hobbyists, making your own saves you money and you may customize it for your needs as well.
Here's how I made a striper:
I used:
- An old (almost dried out) nail polish. The good thing is that it already has a nail art type brush.
- Some acetone and cotton, or cloth for cleaning.
- A pencil.
It really is very easy to make, here's how:
Take of the cap (with brush) of this old nail polish and discard the bottle.
Take off the cap (with brush) of this old nail polish and discard the bottle.
Wipe it clean with a piece of cloth, so that you won't have problem pulling the brush part off.
Clean all residue left using some acetone and cotton balls.
Trim the brush if you think they're still too thick.
Finally snap it on a pencil just like you do a topper. This thing fits any standard pencil.
There you go! Your new striper. What's good about it is that since it's topped on a pencil, you grip on it easier than those thin brushes, allowing you to work comfortably.
