Well, this didn't use much stamping and it really wasn't a card, but it was kinda easy and everyone thought it was cool, especially my nephew who received it.
We gave him $25, all in $1 bills. I taped them together, end to end, and rolled them up, not too tight. Then I took a toiletpaper tube and made a slit in it. I stuck the money inside, with a ribbon attached really well to the outside dollar and had the ribbon sticking out the hole.
Now came the difficult part. I used scrapbook paper and made caps on each end, so the money wouldn't fall out and then covered the tube in the same paper, making a slit in the appropriate place. The ribbon was sticking out and I think I attached a tag to it that had a greeting on one side and said to pull gently on the other.
It worked really well and he had fun pulling and pulling and pulling the money out! Made $25 seem like a whoooooooooooooole lot of money!
