A lot went wrong while making this book safe. First: it turned out to be too high for my book cutter, so i took it to a local copyshop, but they applied too much pressure and tore the bottom papers up and cut it somewhat diagonally. Fortunately there was some space left so I altered my own cutter to allow me for more hight and recut the sides (kind of unevenly). Then I cut out the hole in the middle, but since I had never done this before, it turned out to be very ragged. I decided to smooth this out with a mix of sand and paint, which did a good job on the sides, but totally warped my covers. I fixed this with a make-shift press of stacks of paper. When I closed the book, there was some space between the top and bottom part, but I decided to ignore that. Also, one signature sheet broke at the spine.
This is a Coptic binding with faux-leather covers.
