While the card may look very wedding-ish to you I don't see why it can't be for anniversaries as well. I saw this card on Pinterest and made some minor changes. I used a rubber stamp to create the letters; the original used alphabet and shape beads. Not sure what they used for the ring but I coiled wire into a circle and used a heavy duty glue dot to keep it in place.
