My favourite confetti is biodegradable and light. For example petals, feathers, rice paper shapes, bougainvillea flowers dried and bubbles. I do not like rice because it can kill the birds and looks boring in pictures. I find candy coated almonds hard since I often get hit too. Coins are just well … violent. I also love those over the top suggestion for the exit like the releasing of doves, balloons (though not that eco friendly) and butterflies. Not sure if there is anyone in Italy who releases butterflies for weddings. But they look amazing.
