You didn't choose to send me a card, you're not getting anything in return, and as the saying goes, "beggars can't be choosers."
So send me a postcard, and send me whatever you like. Handmade, freecycled, upcycled, reused, recycled postcards and ad-cards are all welcome too. Please note I have liked every single card I have gotten, without exception.
My only preferences are that you stamp and address the card without an envelope (naked) unless you are sending an item that requires an envelope, and that you at least write SOMETHING, even just a greeting and signature. I like your handwriting even if it's bad.
Please write the Postcard ID two places! Postcards often get damaged, overprinted, and rubbed in machines, especially on the edges, so write the ID two different places to ensure it is not illegible.
