Reposting a question because I haven't received any answers yet.

My fiance and I are planning to theme our wedding around cherry and plum blossoms. One thing we'd really like to do is send out unique "save the date" cards. We'd really like to do something very similar to what you'll see in these pictures:

We like how it's three-dimensional with the petals folded, "blooming" to reveal the message inside. However, we want something more simple, with only 5 petals that have that more distinct cherry blossom petal shape. We want to also put a magnet on the back so our recipients can stick this cute flower to their fridge as a reminder.

Does anyone know where I can go to find something like this? Or any advice on how to make it ourselves?

Thanks!
