Whole miniature rose buds which can be used as a throwing confetti (best when mixed in with petals) or make fantastic table decorations or pot pourri.
Fantastic sprinkled into a hot bath - where they will gradually unfold and eventually fade in colour.

Many venues now specify no paper confetti since they do not want to have to try to clear it up afterwards so using completely natural confetti is a great option.
As with all natural flowers the colour will come out if they get wet so if you are using them as confetti be careful if you have rain on the day (hopefully not a problem you will have!!!).
The 10 pence piece is for illustration only to give and idea of pack size.
