These are the rough folded signatures. There are 5 pages per signature and the ruler is 2 inches ... that's a lot of book. I hadn't pressed the book yet so I was hopeful.
This is just one section being pressed. I divided it all up into four parts then emptied my shelves of heavy books to press everything. There were three Shakespeare anthologies, a Milton anthology, several art history textbooks, an encyclopedia, and a couple of boxes of old hardbacks. I then left it all for two days.
The books are smaller after pressing, but they are still too "oversized" to do my original binding design. I spent a couple of days working out other designs before settling on doing a case-in (glad I got 2 yards of the silk). I really wanted an exposed spine, but I don't think it would be stable enough as the books are about 3 inches thick.
I'll take more pics and post them this week. The marbled papers arrived and I've been hand tarring the sheets to size.
