Greetings and Salutations

Just put up in my etsy store two sets of cards for your letter writing pleasure!
Help save the postal service!

What is the best thing you have ever received in the mail?  Tell me about it and I may choose you, one lucky reader, to get a free set of ALL the cards shown above.  I love a good story.  But you have to leave a comment.  I will let you know who wins on Mother's Day.
