I mailed 2/3 of my cards today!! Bought more stamps and will send the others tomorrow!
I hope that all my cards will arrive unharmed, and that your PO's will except them! Because the 3D-effect, the card isn't flat at all.... It hasn't been a problem untill now, but a strict PO-employer in a bad mood might be fussy....! I also found out that a square card costs 3X as much postage!!!. So I will keep those for Belgium.
