Yes Matt, sometimes the postcards get around the world surprisingly fast.
Some of you commented on my postcard and mentioned that they like the paper I use. I liked that paper especially for postcards because the paper base seems to be a bit thicker than the base of other papers. I use 'liked' here because I think that paper is now gone. I ordered the last pack in 5x7 from FotoImpex yesterday and they do not know if they will get any more of it (at least in that size and surface). Too bad, but there is still some hope that they will be able to stock up. If not, these 100 sheets will last three more exchanges. Since I already printed the cards for round 27 I think after round 30 I will have to go for another postcard paper.
