Currently working on this piece–Regret

Because I use a variety of codes and ciphers, I include notes with each piece. Notes are affixed to the back of the Wallpieces and a separate page included in each book.
I recently noticed that a couple of wallpieces were no longer flat on the wall. The note envelopes were coming a bit open. I could have used a tie closure, but it added a bit of bulk.





Recently found some letterlocking examples and tutorials on YouTube. I have dinked around a bit with them, but some are too bulky.
This is a simple Regency example–



I was curious if seen, would folks know how to easily open and refold. I did a little test. I wrote up my progress notes for my last visit to my rheumatologist. He opened it right off. Asked if it was origami. I like the the folded letter is small and can fit in a pocket.
This is how I am planning to affixed notes to one of my current project.
I will be applying a rust promoter to the washers. Will wait and see if I can write directly on the letter or will need to write notes on a piece of paper and tuck inside the letter.
