It's the holiday season, its the perfect time to propose, below I think are two unique marriage proposal ideas. Welcome to the married life soon...

-quote-

"Christmas is a perfect time to propose. Hang the ring box like an ornament on the tree. When the last present has been opened, say, "wait, there's still one more present." Ask your intended to find it, or simply retrieve it and propose.

Another Christmas marriage proposal idea is to wrap the ring box inside successively bigger boxes so that your sweetheart will think the present is very large. As each layer is opened, the laughs will grow. Get down on one knee right as the last box is opened."

Here is a guide for some proposal ideas. Hope it helps your question.

Unique marriage proposal......

21. Tell her to take time off work and arrange for everything to be covered for a week (but don't tell her where you will be going). Make all the plans for a week's vacation in a five-star resort in Mexico. Propose one evening at a restaurant with serenading mariachis. You can have the diamond ready in your pocket.
22. Order a dozen red roses and pick them up yourself at the shop. Write the card to say, "Will you marry me?" and put the diamond in a presentation box with the roses. Present the flowers during a candlelight dinner for two at home (cater if you can't cook).
23. Mail her a romantic poem from Shakespeare or Browning. Include a photo of yourself on your knees with a diamond in your hand, and write on the back in marker, "Will you marry me?" Be ready, hiding outside her house when she normally opens her mail, and go inside with the diamond in hand when you hear her scream with joy.
24. For the serious netizens -- E-mail a 3-D animated graphic of a loose diamond, with the message, "Will you marry me?" If you can, time the delivery of the e-mail when you can be there in person to see her reaction and get your answer.
25. During a vacation at one of the fancy hotels that leaves chocolates or mints on the pillow each morning -- Sneak back after she leaves the room for breakfast, make the bed, put out the "Do not disturb" sign. Leave the diamond in a special box on the pillow in place of the mints so she finds it when you get back.
26. If no kids -- Hide the diamond in a box with your proposal message in a place she will certainly look during the day -- such as in the butter dish if she eats toast every morning, or in the silverware drawer before dinner, or with her makeup in the morning. Try to be there when you expect her to find it.
27. If neither of you are afraid of heights -- Arrange with a local adventure guide for a private hot air balloon ride for just the two of you (and the pilot). Schedule the time so that it covers either sunrise or sunset. Some companies provide a full meal with a table setting and the works. Present the diamond in a box as the dessert at the end of the meal.
28. Arrange for a day at a private beach together, building sand castles or digging for shells. On the night before, write a love poem on a peice of parchment paper, roll it into an antique bottle with a cork, and bury it in a well marked spot in the sand near your diggings. Be sure you "find" the bottle as you dig together. Open and read the poem, then present the diamond from your pocket and ask her for her hand in marriage.
29. Only for the really bold and mature relationship -- Surprise her with a proposal and wedding all at once! Schedule a vacation in Hawaii where marriage requirements are less. Arrange every detail of a full wedding through the staff at the tourist bureau and your chosen resort hotel, including a dress and relatives. When you go out for dinner, have everyone hide nearby, listening for her answer and their cues. As soon as she answers your proposal, start the wedding on the spot!
30. If she wakes up each morning to the clock radio, arrange for an ad on her usual station at just the right time so she hears your proposal when she wakes up in the morning. Try to be at her door (or beside her) when she hears your public proposal, and have the diamond in hand.
31. If she is a school teacher, you could propose with all the school listening. Get permission from the school principal. Record a videotaped proposal and play it over the school video system, or make an announcement over the intercom. Then go to her classroom and give her the diamond with everyone cheering.
32. If she loves puzzles, disguise your proposal as an anagram that works out to read: "Will You Marry Me?" and pretend to work on it with her for entertainment while you are waiting for dinner to arrive at a fine restaurant.
33. If she likes cute stories, you could make a storybook of two animals (with your names) falling in love and getting engaged. Take two stuffed animals, put a coathanger in their backs to make them hold a position, then set up the animals to act out the story while you take photos. Type the words to the story on your computer and paste them to each page. Write the last page to say, "Will you marry me?", with a picture of the diamond in its presentation box. Take it all to a printer to have it bound as a booklet, then present the book at a private moment at home. Be ready with the real diamond when she gets to the last page.
34. If you have a talking bird or parrot, train it to say, "Will you marry me?" And make a big show with the new words he has learned -- at a romantic moment.
35. If she has deep ties with her family: Make up a special Christmas or birthday present when she will be traveling alone to see the family without you and send it with her as a gift to open with her family on the big day. Place the diamond in a presentation box between two plush velvet pillows into a gift box. Type your proposal on parchment paper and pin it to a pillow next to the diamond, and wrap it all as a gift. Be near a phone during the day when she will open the present.
36. If she has been waiting for her "big chicken" to finally ask her: Arrange to meet her for lunch where she works. Rent a Big Bird costume from the local theatrical shop and wear it on the way. She won't know who it is inside, so write a card that says you have been sent by a dear friend (so she won't recognize your voice). Show another card that asks her name to confirm she is the right woman. Then give her a paper bag with a large plastic easter egg in it (one of the ones that open with candy inside). Inside the egg, put the diamond box and a message, "Will you marry me?"
37. For skilled scuba divers and snorklers: Arrange a special dive with a few of your best friends. At the end of the dive or in an especially beautiful area, write, "Will you marry me?" on your diver's slate and show her. When she nods in agreement, slip an inexpensive expandable ring on her finger. When you go topside, have the real diamond ready nearby.
