I have received quite a few postcards that have been mounted on one substance or another. I'm sure this is acceptable. Just check www.usps.gov to see if there are other requirements (like the line down the back between the address area & the note area).Originally Posted by Flotsam
I'm sure that Nigel will respond about the quantity... I've found it's generally between 18 and 25 postcards.
Right now is the next round! Check the very top of this post to see Nigel's schedule. You are just in time to get in on this round!
I, for one, hope you do!
