I made a card with a pop up ball inside.
The card base is held closed with a paper band.
When you open this card the ball pops up.
See this video on how the mechanism works: https://www.youtube.com/watch?v=aG13l6wq6NI
Unfortunately I do not have this great die from Sizzix...
The band is decorated with punched Nellie Snellen flowers and leaves, the same as on the inside of the card.
All sentiments are stamps from Marianne design saying on the front "its your birthday", inside "enjoy every moment" and on the ball "Have a nice day".
The large butterfly is from Marianne Design (EC0095) cut by hand and the little butterfly on the ball is made with a punch.
I attached yellow rhinestones in each flower heart.
