What do you do with 500 old business cards?

I got crafty one morning with Anna.

I told her we were going to make a sign for dad out of his old business cards from when we lived in Detroit. I wrote out We Love you Daddy. Notice that its Dad. Anna did the dad all on her own so I tossed out my Daddy cards I made. Its so much sweeter with what she did.

That is so cool, she can write dad and I didn't even help :)
