One of the tricks we learned was to make a round indentation so that you can easily grasp the book when taking it out of the case. But that would mean that you'd grab the book by the lips of the statue, so to speak -- and the most striking feature of the cover is the face of the statue. So I decided to cut out the face, so that you'd see it from outside of the case -- a decision I came to regret later... I did have a beige-like linen in stock, so I decided to use that for the outside of the case.
Using a caliper, I took the measurements of the book. This has to be precise on a tenth of a millimeter: you want a case that fits snug, but not too snug: you have to get the book out of the case too! But if you line the inside of the case with paper (which I did), then you have to take the thickness of the paper into account as well! That means lots of calculations (hooray for spreadsheets!) and very, very precise cutting and glueing.
The finished case, with the book inside.
The book half out of the case.
For the back, I cut out the outline of the helm. This was a lot of work, and all the sharp angles didn't help with covering the side of the board with linen! You can also see that the case covers the book until half of the space between the spine and the cover (in Dutch it's called "kneep", I don't know the English bookbinding jargon...).
The side of the board is covered with a thin strip of linen that I cut to create a rounding. The front of the board is covered with the same linen. Using a sharp knife, I cut out the shape of the hole...
This was actually the hardest part: getting linen on all the bare edges of the board.
I used drawing paper to trace the logo, and used my gilding pen to recreate the logo on roughly the same spot. Of course, I made sure that the logo wasn't at an angle before I began!
I'm quite proud of the end result. It's quite unique, which also presented me with unique challenges. I learned a lot from this. And my bookbinding teacher was satisfied with the result too!
