When one thinks of using flowers to be romantic they usually imagine a bouquet of roses or other flowers. In my opinion, a more romantic usage of flowers is with their petals. So, I suggest you some ideas on how to use them:

- Tossed on the bed
- Floating in the bath
- Making a path
- Decorating a dessert
- Rose petal massage
- Writing on rose petals
- Covering yourself with petals, without any clothes
- Used to pack a gift
- Made into a candle
- Create a bar of soap with petals
- Bring petals to a restaurant and put on table
- Sew onto lingerie (don't dry ;))
- Inside an envelope with a love letter
- Floating in a bowl of water
- Placed in a book your beloved is reading
- Tickle your beloved with rose petals
- Surrounding your beloved with petals while he or she is sleeping
- Put in a glass of champagne

Do you have any other ideas?
