I've seen several post about this subject and I would like to share what we are doing for ours. It's called a Cord of Three. You can read all about it at Godsknot.com. Its a gold ring with three ropes attached. White, purple, and gold or yellow. The groom holds the ring while the bride braids it. It represents God, the bride, and groom coming together as one. I thought it was pretty neat and the website provides all info needed on it.
