Technique: Coptic stitch binding, one long thread, one needle
Cover board: Two layers of cardboard from old archival boxes, glued together. (I have a huge pile of never used boxes. From one box I get the four cardboard pieces for one book.)
Number of signatures: 6
Signature paper: Clairefontaine Pollen Ivory, 120 gm/m2, 12 sheets.
Cloth: Canapetta 1421
Paper inside cover: Remondini rombi, from Grafiche Tassotti, Italy.
Glue: Coccoina, Italian made glue from potato-starch
Thread: Irish linen, waxed with an old candle
Comment: I think that the size of this codex is optimal for this technique, (A6). Of course you can add signatures up to eight without problems.
Flaws: I accidentally turned a couple of signatures upside down so there is a slight misalignment if you look carefully. When i fastened one end of the thread I happened to sew through the thread itself and it was jammed beyond rescue, it can easily be seen on the pictures.
Comments are welcome! Kommentarer även på svenska välkomnas!
Thanks to: Djura Bok & Pappersverkstad, http://www.djurabok.se/internetbutik/ for providing me with materials and basic tools.
Epilogue: I have now made a second codex, with eight signatures 128 pages, without major flaws but the paper inside the back cover isn’t exactly positioned. When I get the right light I will try to take better pictures this time.
