An update...

My cards were printed last week. I used old Agfa paper, the same I used a few rounds back. Back then, I had a big "curl" problem. This time, I tried drying using the print dryer, the result being that instead of curling inwards, they are now curling outwards. Not sure that's a big improvement...

They have spent about a week under a big heavy stack of books, I hope that helps (haven't dared to look yet). Depending on how bad the curl is, I might decide to send them in envelopes.

I have received some nice cards already, I will comment on them as soon as my own cards are posted.
