I love pink and black together and because it's for a teenage birthday, I added some bling to the butterfly!
The ribbon is from Poppicrafts (which has sadly closed down) and the butterfly is a Unity stamp. I lifted the wings slightly and curled them under by rolling the edges over an embossing stylus (you could also use a pencil) then I put some silicone glue underneath to keep them from flattening. The sentiment is a stamp from Elzybells - I love it for it suits a lot of occasions :)
Have a lovely day!
