    At least its not reminding you of 1980s BBS. What are your favorite qualities of an of the 3 versions? What could you live without. I'll try to touch it up tomorrow!

    I think v2.6 is my favorite version so far. I could live without the knowledge that I inflicted v2.7 on the world.

    In practice, I think the private key will need a minimum of 3 lines of text, and the public key 2. I should try throwing a fake key in there. I also need to do some sticker tests once my labels arrive.

    I changed up the noise pattern to something more appealing on the eyes as well as revamped the panels that would be outward facing. I think that the private and public key boxes are long enough if you use a 6 or 8 point narrow or condensed type font. Also added a shadow to the "Rethink Digital Currency." What do you think of this version?

    Hello @Freedom2Choose if you have a chance check this thread: https://forum.decred.org/threads/online-address-generator.112/
    They could benefit from your design expertise...

    Test run on trifold v.3
    trifold_wallet_V3_testing.jpg
    (using Bitcoin addresses generated by walletgenerator. Also, they don't match.)
    The text is 11-point, Lucida Console(fixed-width) font, and the objects haven't been resized(that would be cheating). I wouldn't risk going any smaller. The public key fit nicely into the bar after I moved the label and widened the bar just a little, but the private key required 2 lines to fit into the available width constraints. I also had some concern about the size of the QR code and printing legibility, so I tried turning just that cell sideways, so the QR code could take up as much space as possible.

    In this one, I had to break the private key into 3 lines, but the QR code is considerably larger, which should improve the chances of it printing well even on low-end printers(yes, I'm still fixated on the thermal printer)

    I don't think there's any way we're going to avoid breaking the private key into multiple lines at very least. In this example, I've deliberately kept the line widths uneven, as this should aid the human eye in manual transcription should reading the QR code fail.

    For the obfuscation patterns, I would encourage the use of a pattern with as much contrast as the QR codes themselves have (solid black to solid white). Otherwise a photograph of the outside of the wallet could conceivably be manipulated to show the insides without showing physical signs(cut tape or torn paper) that the wallet has been opened.

    I was playing around with one of those fancy QR Generators and I think this would look nice:

    It would make it even harder to read through paper.

    The generation algorithm is harder but I think that the gain in aesthetic and security would be worth the effort.

    I really like that QR, and I learned something new about the obfuscation pattern. I found a stray puppy wandering down the road tonight so hopefully I get some free time in the near future.

    Fortune! I got a new phone, and my printable labels arrived today. The labels are a pain to get lined up. The printer advances 1/2 inch every time the hatch is closed, but I think I've got it figured out.

    I was able to get a 1-inch "private key" QR code printed fairly well-centered on a label
    Phone picture is terrible.jpg
    Yes, it's a terrible picture. My new phone is cheap. Anyway, that sticker should fit comfortably in the public and private key slots, and it doesn't look like it from the photograph, but my phone can actually scan it semi-reliably from about 3 inches away.

    Looking forward to performing tests with a "real" wallet once ink arrives for my other printer.

    Also I derped. If we swap the locations of the Notes pane and the Public Key pane, then users can tear off the public key and give it away like I mentioned in my first post in this thread.

    That's easy, though. I don't think it really needs an illustration.
