I'm gearing up to send out some postcards (made a promise to my local kid-lit group, so now I HAVE to do it) but from what I hear the format, layout and all sorts of other stuff can differ drastically from artist to artist.
So I'm curious! What do your postcards look like? Single sided? Double sided with an image on one side and info and such on the back (like a normal postcard)? Hand written? auto-mailed by an online entity en-masse? Personalized with calligraphic doodles? Stickers? Stuffed in a semi-clear envelope with pins and other goodies?
Post an image if you can (or just tell me what you do, that works too)
