If you have problems let me know. i wrote the pattern for myself and took shortcuts. i tried to expand the explanation for others, but only you can tell me if i succeeded.

It is easy to modify this pattern by decreasing the number of caston stitches in twos and removing the two stitches from the two seed stitch ends or the two border columns of the cables through which i have woven a ribbon; depending upon how much book height you want to remove.
