The card is a white textured card stock from houseofpaper.com.au. I had a felt heart from Rainbow Lollies that matched some of the colours, then I added some paper frills (doodlebug designs inc) and stamped "happy day" in grey ink. I also added some glitter to the turquoise paper frill.

The card is blank inside and a white envelope is included.
Thanks for looking! :)
