Great point with a simple answer. I don't have any print samples yet. Turns out the Printing On Demand companies I was working with enjoy taking of several weeks on either side of Christmas. I'm pretty miffed about this myself, frankly.
To further put your mind at ease, I have extensive experience working with printing-on-demand and dropshipping services. I've built out complete pipeline integrations with IngramSpark, Ingram LightningSource, and ZenPrint from scratch. If you keep the journal, you will get your book. Guaranteed.
I've added an FAQ (should be percolating through the Internet as we speak, with some very basic details about the book. For anyone who is interested, the book is a 5x8inch (203x127mm) hardback with a cloth cover and professional typography and layout. You will be able to personalize the cover color and book title.
Thanks for your comment!
If anyone was even interested in the premise in the end they want the deliverable... So show it.
