I don't like having things attached to me, so I made a small scroll book that fits into my satchel. I took a cheap 4x6 photo album, wrapped it with some faux leather in the way that I wrapped textbooks as a kid, and I put the scroll reps into the sleeves. I even made some simple reps to make them stand out and faster to sort through. In the future, I'm going to print them out of different colors of paper to make it even easier.
