Alas, the QR codes are about as small as they can get right now. In fact, I probably need to bump them back up in size, because I'm having trouble scanning them in anything but really bright light and perfect distance.
I can tune down the error correction and capacity probably one more notch, which lets it use a coarser dot pattern and less DPI. But, I think leaves about 50 characters of space for an URL - that's really not enough.
Shit - I hope that doesn't cause issues at the Faire... Sorry, I should have tested with a wider variety of phones.

Well, they still work, they're just more fussy the smaller they get. A little bit larger, and I can scan them at about 5" with a dim lamp on. Worst case, the alphanumeric claim code is still usable on the front page.
We may have to provide the option to use 2'' x 2'' avery stickers, they're just more expensive.

After some experience trying to print the 1.5 x 1.5'' stickers, a larger border is needed to address normal printer shift that occurs on most printers. A 2mm border should be sufficient to address the issue.
In addition, we should test the smallest possible size for the QR code itself to still work with QR readers - we may be able to further shrink the QR to allow the picture to be bigger.
