I would like to know more about the making of these post cards. I think swapping (mailing) them would be fun to see.
If it was 6-7 seasons ago, has the UPS changed any of their standards for mailing them? I can be wrong, but I thought to save money recently (2010 maybe), they removed some of the places that did hand processing/stamping.
Still this would be fun, I think. maybe I could use my stash up some. :)
