Mamaegg, I have made this card before and it's kind of tricky. You either punch a whole with the word window paper punch from SU or you can cut it with a razor knife. You then put a penny on the back of your slit a dimensional on that penny and then a penny on top of your dimensional, so your dimensional is in the slit. Then, you take a glue dot and glue your design on top of the penny and it should then slide. I hope this make sense, if you have any questions let me know.
