A long strip of the black fabric that makes the seams could be sewn between two Organizer pouches and 6 or 3 binder style rings could be glue/fastened to it.

The long strip of black fabric that would hold the ring could extend and become a anchor for a zipper that would close the organizer.

I have had no luck finding an organizer that is not leather, not top heavy, not gaudy and that has side pockets to organize my stuff such as an extra pad of paper, stamps, address labels, business cards etc...

When I was looking (again) at the Organizer Pouches, I said those are the answer.
