I've got TONS of baby food jars that I put stuff in - random little things like sequins, confetti, buttons, brads- and then turn the upside down (with the lid on of course) in a drawer in an iris cart.
I like to have EVERYTHING labeled but I change up my organization often (ever feel like you organize more than scrap?) so to allow me to change my labels I got some of those sticky back vinyl business card holders that you can slide cards into and put those on the fronts of stuff so I can change it out as I see fit. It works REALLY well. There are some binder labels too that are pockets for putting things into that fit on the fronts of the artbin's that are 13x13 (fit 12x12 papers PERFECTLY).
Like someone else said, if you paint a mixture of stuff all one color the all of the sudden go together. I went a different direction and want to be able to see INTO my stuff so I went translucent white.
