I bought some petal type ones from Confetti but they were a bit scratchy, got some heart shaped pockets and stuffed them and put them in a wicker basket (£1 from the pound shop!) and got the MC to hand out whilst we were signing the register.
I bought ours 'cos PL don't allow you to chuck it outside so it meant I could control when the confetti shot was iyswim!
Not long now, how exciting :-)
