For example, the X Book (MHB, 32) showed the word "each" on the cover, with "unique" and "structure" facing each other.
The T-Cut Book (47) shared the same opening of "unique" and "structure" as the X book (but left white spaces so should be printed on two sides for a better effect). The last two words had to share a page to fit.
When I folded the Pants Book (36), however, "each" and "unique" shared the space. The two words looked too heavy together, so I chose a lighter typeface for "unique."
X Book: Each unique structure opens unique reading possibilities
T-Cut: Each unique structure (blank)(blank)(blank)(blank) opens unique reading/possibilities
Pants Books: Each unique structure opens unique reading possibilities
