I found the coolest aquamarine book-binding paper and I wanted to make a hard-bound journal with it. I also wanted to include a leather bookmark and burnt copper accents. Here's the result:
Before pasting the boards to the cover paper, I used an X-Acto knife to cut grooves in the davy board, forming ridges. I centered the copper eyelets between the grooves, secured the leather strap for the bookmark, and then assembled the inside of the book.
I call it "Aquasteel"
