I don't have a lot of makeup brushes, but I do have a few. They just kind of roll around in my makeup back and get all kinds of dirty. I've thought of getting a brush holder bag, but they're expensive and, well, I'm
cheap frugal. :) I love Pink Polka Dot Creations' idea to make a brush holder out of a terry cloth towel. Cheap and easy to clean!!
