It's become really popular now to throw rose petals instead of paper confetti. I made cones of real rose petals at my wedding for guests to throw, it's such good fun.
Choosing rose petals are great for several reasons:
You can colour coordinate the petals to your wedding colour theme. Boy do this company have plenty to choose from, I would be surprised if they didn't have your colour theme.
They show up really well on your photographs. Because they are larger than the traditional tiny paper confetti pieces they can be captured on film.
Finally if you choose petals that are real or freeze dried (as apposed to silk) then most venues will let your guest throw them. Many people are now concerned about the environment and not leaving a mess behind, so what better way to celebrate than will real petals.
Throwing confetti at the bride and groom goes back in time, long a go guests would traditional throw rice grains. I'm not sure many brides would be too happy to be showered in rice nowadays!
Any types of these rose petals add colour and a finishing touch to your table decorations as well. This is a great place to use the silk ones as they will look great all day long.
