I got these to help organize my knitting patterns. I thought the color bars on the side were a great idea! I could have several patterns in one folder and use the color bars on the side to make it easy for me to tell different patterns apart. Sadly, the color does come off with a little rubbing.
I use the sheet protectors on the patterns because I use Vis a Vis markers to mark on the patterns - notes, my place, corrections that kind of thing - and I can wipe them off easily! (That is how I found out that the color bars come off)
