Here is the card I made for her using the Petite Petals stamp set and matching punch:
I stamped the flowers, punched them out, curled up the petals, embellished them with an adhesive rhinestone, and mounted them onto the card with foam tape to added dimension. To the centre flower I added a little "16" tag punched with the Jewellery Tag Punch...and that's it.
Sweet and simple. :)
