Don't you just love getting a big beribboned gift box with your name on it? The excitement of big presents and gift packages cannot be overestimated, and make for a perfect marriage proposal.
On a birthday, Christmas, Hanukkah, or other gift-giving occasion, wrap the ring inside successively bigger boxes. Your sweetheart will never imagine there's a ring inside such a huge box, but as each layer is opened, the laughs will grow. If you do too many layers, there might be some annoyance as well, but all of that will fade when the last box is opened. You can prolong the experience even farther by wrapping the ring inside layers and layers of tissue, or inside Russian nesting dolls. Get down on one knee right as the ring is discovered.
Pros of this marriage proposal idea: It's fun and funny, and uses the joy of gift-giving occasions.
Cons of this marriage proposal idea: Your sweetheart might be annoyed at having to open so many layers! But I bet that won't last too long.
