Check out these photos of a couple early organza bookribbon prototypes I made a while back. One is longer and made with wider ribbon for large paperbacks and hardbound books. The other, thinner version is shorter and geared toward mass-market paperbacks. These are both made with silver-plated components, Swarovski crystal, and rainbow fluorite gemstone beads and focals.
The bits of the ribbon the silver ends are clamped on to are NOT typical. The final version will have a much smoother crimp without the any extra material in there to hold the crimp in place (they will be properly glued instead).
The jewelry bits attached to the ribbon ends will be taken over to new ribbons and put up for sale soon, but I have lots of ribbon colors and gemstones to work with. Feel free to contact me or comment with requests.
