Today on 365 cards we were to be inspired by this ad.  When I saw all that green, $Money$ popped into my mind!  I remembered on this site://www.ruthannzaroff.com/mirkwooddesigns/templates.htm there is a money holder template.  I printed the “New US money version” on green paper and cut it out.  I still had to fold the money to make it fit right, but I really like the outcome.  I added a small magnet to the bottom lip to make it stay closed, but you could use a money clip as the gift and keep the card closed with that as well.
