make a puzzle out of posterboard with the words will you marry me on it. In the house, make a trail of rose petals or hershey's kisses that connects the different puzzle pieces. At each puzzle piece leave either roses, notes or poems, or something special to both of you. At the second to last piece of the puzzle leave a dress
(either your favorite on her or a new one) and the things she will need to dress up with like shoes, earrings,a strapless bra, etc. Leave a note telling her to please put them on before following the rest of the trail. When she gets to the last piece, she will open the door to find a candle light dinner for two with rose petals everywhere and you with the last piece of the puzzle which has the words marry me on it. Then you could get down on your knees and say "you complete me" ( like a puzzle)and ask. another idea is that you could have the puzzle say you complete me. By the way this is totally original. I came up with it today when my friend and i were thinking of cute ways to ask a guy to winter ball--but im not gunna use it---its too special. Good luck !
