Favorite organizers: "The best place to buy this kind of stuff is the craft store. They have the perfect-sized bins for makeup, because they are wide instead of tall. (Deep bins end up with your products in a pile at the back and you can’t see items in them.) Scrapbook containers are great, too, since they are narrower, and you can neatly stack them. I also have this scrapbook rolling cart with drawers that pull out. When I need to use stuff for projects and don't want it all over the place, I just roll it out."
