I am working on authoring, printing, and binding a microbook with completely legible print. It’s going to be a new story; and of course, it will be bilingual (English/Japanese). Read front to back you can read the English version of the story. Read back to front you can read the Japanese version. The approximate size is 20 mm high by 25 mm wide by 5 mm thick.
I’m still working out the kinks in the template, and I’ll probably end up making a jig to help with trimming the book block at the end.
