You've all been so good about remembering to put a layer of non-stick paper in between your postcards and it really pays off.
We had our first super-humid days of the summer this week and not a single postcard got stuck to anything because everyone remembered to include parchment or waxed paper, or deli paper, etc.
This time last year (before including the "layer" suggestion in the swap rules) I was delicately prying postcards apart on a daily basis, and we had some casualties.
So thanks, and keep it up!
