best way to store foldables

I am pretty sure this is the reason I took a vacation from foldables in the first place...I had no idea what the best way to have the kids store them.

We are making out okay currently by copying a sheet with a header on it and having the kids glue the foldable to it. From there, they add the page to their 3 ring binder with the rest of their math stuff.

I MIGHT (notice the emphasis on 'might') have come up with a solution for random, vulnerable foldables for the future. I am trying it out with the students I am tutoring before and after school. Rather than adding the foldables to a sheet of paper, we are gluing/taping them into a composition book, hence creating a customized, unique math textbook that can be used as a reference for this year and beyond. I wish I had thought of it earlier, but now I have the time to try it out with tutoring and hopefully identify any glitches prior to implementing the idea with close to 100 kids.

Any thoughts are welcome.
