Thank you Gerardo- I reached out to Michel and he pointed me toward the bar envelope by Frances LeVangia(http://www.metteunits.com/EnvelopeDiagram.htm). Then I developed my own using the same locking mechanism for the bottom of the envelope.
You can see what I came up with on my instagram here <https://www.instagram.com/p/Cm2RASMp3xI/?utm_source=ig_web_copy_link>. It is super simple so it's likely I'm not the first to stumble upon it. I have also uploaded the folding sequence there. Thank you to all who lent a helping hand, and have a *HAPPY NEW YEAR!* On Tue, Dec 27, 2022 at 6:56 AM gera...@neorigami.com <gera...@neorigami.com> wrote: > Ian is asking for origami envelopes appropriate for standard-size trading > cards.
