Below we have outlined the quantities of petals sold in the different sized boxes. Please note that 2 litres is our smallest size and is recommended for personal/bridal party confetti or for small decorating or crafting jobs. Please allow 2/3 of a cup to 1 cup of petals per person for confetti (this is what will fit in a 4x6 inch organza bag or a standard petal cone).2 litre size - 10 cups4 litre size - 20 cups6 litre size - 30 cups8 litre size - 40 cups12 litre size - 60 cups16 litre size - 80 cups 20 litre size - 100 cups24 litre size - 120 cupsWe have a triple check system in place to ensure that every customer receives the correct amount of petals on order and we use standardised kitchen measuring cups and a litre jug to measure the petals when fulfilling orders, which is standard practise across the petal industry.We always advise that you 'fluff' up your petals by hand when they arrive to you, as they might settle in transit.
