I am one of Jehovah's Witnesses and provide
Leather binding for Jehovah's Witnesses.
We have been in leather bookbinding for over 4o years and are a
manufacturer of soft goat skin leather book covers. The goat skins come from England where they are given vegetable tannage. They are then imported to the USA.
Each item is hand crafted with attention given to details such as, hubs on spine of books, gold or silver trim applied by hotroller to edges of books, ample ribbons for place markers, then lastly put in a press mold to emboss the window frame around the outside perimeter of book. The recipient's name is also embossed in gold on the cover of the books.
All different books from the Branch are done the same way. So if you see what pleases you, yours will be the same.
