I used the black colors for my Halloween cards and it was excellent. The paper gives such a nice feel for making cards. Very sturdy and substantial.
This paper is meant to be written on with chalk. If you want it to look "used" trying using some chalk on it and wiping it off. It looks cool. Don't expect letters written with chalk to stay on it very well unless you spray some kind of fixative on it.
I was excited when I first saw this paper, however, when I received it, it did not look like the picture. It does not have the chalky look I had wanted for my son's school pictures. The colors are bright and in no way look like a used chalkboard.
