The Brushes That Come With Blush and Eye Shadow
We hope you learned this lesson back in high school, but here it is anyway. When you buy blush or eye shadow, the first thing you should do is throw out the brush or sponge-tip applicators that are packaged in the case.
Even the best blushes come with really low-quality brushes, and those sponge applicators are basically useless for eye shadow. Invest in your own brushes -- they don't have to be expensive, but pretty much anything will be better than the generic stuff.
