The postcards I promised are ready.
I'll print them myself on white Canson drawing paper (180g) on size A4. Once folded in two, a card will be 14.7cm x 21cm (5.75" x 8.27"), portrait or landscape following the model.
I wrote quotes in English but I can print them in another language, personalize or change completely (provided you give me exact words!).

#5 and 12 are adult; #8 is definitely for naughty grown-ups!

Christmas

1."Merry Christmas"
2."We Wish You A Merry Christmas"
3."merry X-mas"
4."Have A Magic Christmas"
5."Have a slashy and merry Christmas"

Christmas & New Year

6."We wish you a Foxy Christmas..."

New Year

7."Happy New Year"
8."I wish you a slashy New Year"

Valentine

9."I love you so much than I miss you... Even when you're there!"
10."It grows as my love for you"
11."Wanna share my heart? Be my Valentine..."
12."Did you deserve a spanking? Be my leather Valentine!"

One card is 2.00 € (2.35 US$ or 1.35 UK£).
Postage rates are a little complicate but one card weighs 14g.
Using "Postexport" special envelope (cardboard) would be 2.05 € for EU and 6.90 € for North-America (max. 5 postcards) - 2.85 € for EU and 8.30 € for North-America (up to 32 postcards if I'm not mistaken.)
Using simple envelopes (tear-resistant) would be cheaper, but the calculation is different for 1, 2, 3, 4 or 5, 6, 7 to 13, 15 to 35 postcards... Please e-mail me with what you wish and I'll tell you LOL
