Ask:
Thank You Big Sister.... I love the card, did you make it?
Hmmm the mystery begins.....I think we live in the same state?

Answer:
Your welcome. I wish I could say I made the card, but I actually got a package of handmade cards for a gift, they come in handy though.
You are correct we live in the same state, actually fairly close. I worried about the post mark, but I figured it was a great first clue.
Look for more clues.
