Laura also says most women just need one good small brush. Which one to choose? A couple of small brushes that Laura suggests are a broad, tapered crease brush or a small ponytail brush. A crease brush helps control eye color along the crease of your eyelid. A ponytail brush is great when you want to lightly layer and blend color along the crease of the eye. If eyeliner is more your style, then consider a pointed eyeliner brush that allows you to control the thickness of the liner by how much pressure you apply with the brush.
