A dear friend of mine had gotten engaged to a wonderful man, and they asked me to make their wedding bands. He wanted a simple, straightforward domed band; and for her ring we decided that we'd match the shank of the elegantly understated engagement ring that her fiancé had given her.
Ever one for secret romantic messages, I forged the two rings from a single length of gold wire stock. I first took a piece of it to make his ring, and then drew the remaining stock down to a narrower gauge so that I could make the double-domed band for her ring. Hence the rings (like the beautiful couple) are vaguely doubles of each other, distinctly different but cut from the same stock and forever united.
