What you are going to need is your diecut, a buckle that is made of card stock, a piece of paper long enough to fit your card, glue and a card.
Place your paper through the buckle, make sure the paper slides through. Glue the buckle to you diecut. Let it dry and then try again to see if the paper slides through the buckle.
If that is dry, glue the two edges, of the paper, to the card. I used double sided tape for that.
After that I used a Fiskas grass punch to additional green paper to cover up the slider. Now you are going to need stickers, stamps, or my diecuts to add "flare" to your card. I ended making mine a birthday card.
Hope this works good for you and you can create some really cute cards like this. I even made a balloon card like this where it floats up.
Have fun and enjoy....
