It is based on a combination of something I saw one of the message board members post and sort of what I have seen with the scraprack system.
I use enclosed hanging file folders and sort how I think when I need to find something. The strange advantage - if the wrong folder is opened, I am tending to remember more of what I have :).
The above are some of the hanging file folders. I have two boxes for swaps. ATC's, cards and dimensional flowers (for the most part) are stored in a different boxes. The flowers I am used to looking through, the ATC's - I recently found their box. I will probably sort them into these folders since I like to use them on pages/in mini albums.
