Sorry Cindy. I am a dissenting voice on this one.
I love the idea and it has special meaning to you because you did it and your parents did it as well.
It just does not transfer to the current generation. People do not write nearly as much anymore. The computer has changed all kinds of communication.
So with that in mind and knowing my own children in their 20's, it would be a lovely thought but not used.
I am not hear to hurt your feelings. I just wanted to give my reaction.
