finally i got the eyelet-twill i had ordered some weeks ago and now i could finish my raven book. i sewed two parts of the twill to connect the three pocket-pages.
left pic shows how the book looks from outside. added two raven-charms (one of glass + soldering; one made of silver) to complete the book.
right pic shows open book with the eyelet-twill.
