(July 2013) I did this project a few years ago and have posted updates here when I had them. This time I have a video.
The cardstock deck works like a paint deck. You put small strips of each color of cardstock on a strip of white cardstock. The colors are arranged light to dark or dark to light in one color like all the reds together, all the blues together, and so forth. Then it is easy to match up what color cardstock goes with what designer paper.
The video shows options for doing this via the Word document attached or without a computer at all.

I use my deck all the time! The file does contain more than SU!'s current colors - many retired colors. You can add or remove color names to suit your stash.
