Here's a link to the braiding pattern - the soutache, and the "frog closures". It's one page in PDF that should give you a braiding pattern to fit into a 4 cm border at 100%.
The soutache pattern, I admit, is slightly different from what's on the jacket, where it's more... rounded. This is what I worked out in Inkscape, while trying to fit it into the 4 cm border with a 3 mm wide line - to accommodate my soutache. I guess the original braid was narrower. (The line in the final pattern is narrower, too, but I had to try it out with the 3 mm, to make sure it does not overlap or anything.)
It's the front centre corner of the jacket (turned 90 degrees). In the rest of the jacket, the pattern just continues. I haven't tried deciphering the sleeve pattern from the photos; that would take forever and I don't want to duplicate it anyway.
The closure is so complicated, the resizing from the tiny picture in the book - especially because it's imprecise there - took me some time... I still haven't really figured that pattern out. Maybe I'll cowardly back out from that to something less complicated...
