This is a freebie I'm sharing for any of you who have tiny little papers you need to file. In my case, I had a bunch of little cutout fingering charts used for teaching scale fingerings on the piano, and I wanted to have a nice way to store them in my desk drawer. I came up with this solution. The finished file folders, when folded, measure 3.5" in width, and 1.8" in height (2" tall if you include the tab).
To use, just trace, cut out, and fold! I did a post on my blog about this which may help you understand how I use them and the process for making them. http://pajamapedagogue.blogspot.com/2015/09/how-to-make-tiny-file-folders-for-your.html
