The girl is a sugar nellie stamp. Dont you just love her little skull on the bottom of her dress!! The flower are from Stampin' Up kit Vintage Vogue, which you can order from Jo. The skulls that make up the centre of the flowers are from Once Upon a Stamp, but I'm not sure if they are still available.
As for the backing papers? No idea lol
Enjoy what's left of your Sunday! Thanks for looking :o)
