The roll-up pouch containing my makeup brushes has been getting a little overcrowded as of late, so I started storing my seldom-used brushes in an old pencil container. (The cup kind, not the kiddie pencil sort.) This got me to thinking about other storage options for my collection of these trusty cosmetic tools. Whether it's a well-stocked train case for hard-core makeup users, or a cute compartmentalized pouch, where do you keep your makeup brushes?
