CREATIVITY AND ORIGINALITY my friend are key when it comes to this. Your girl will want something that awes her but also seems like it is combing directly from you. So don't pull it off of YouTube otherwise it won't be the same. Sure watch some videos on YouTube to get some ideas but make sure they are yours and that will make it that much better. Then there is no way she can say no.
Buy her flowers then make sure it's the kind that comes with an envelope and card to write on. Write down "look at the steams of the flowers" but fee free to personalize it slip the ring around the steam. You might have to put more then one steam through to keep it from falling of. And make sure you cut the thorns off. GOOD LUCK!
Ok listen to this one.... My friends older brotger just proposed to his gf and they both r in college, and one day he left a note on her door and told her to go to another place on campus,and tht note led to another and so on. And the last note said to come to hill and my friends brother was sitting on the hill on his knee, and she ran up and he said"will u marry me?" and she said yes!
