I found this idea in a card-making magazine. Thanks Carole!
Front of my card: (I know, I know, I could have done a better job of letter alignment)
Since my recipient will be 51 this year I thought 49th birthday was more appropriate. (My opinion committee agreed). I will sign on a sticky note so she can recycle and reuse this card if she so desires. Note: this card was made with paper scraps only. No full sheet of paper was harmed.
