Here's what I use. I cut these for members on this board only. I love the idea of the file cabinets, but in the end I think they take up as much room as a bookcase would. Also, I know the green hangers are not acid free. That concerns me a lot.
Don't know if something like this would work for you, but you can check my feedback and see that several of us here use this method. Just please whatever you do, be careful of using anything that can hurt your fabrics.
