I had a request from a client to turn her husband’s Australian Army major’s crowns into a set of cuff links as a surprise for him.
After a quick refresher to make sure that the melting point of the metal would not be too low to take the soldering, I removed the existing toggles, soldered cuff link backs on the crowns, et voila! (OK, I confess I had to change the direction of the links after a little misunderstanding, but hey – cuff links achieved!)
