Thanks Serigo, that is of my youngest daughter and my first full from life, so I know it has some major technical problems, plus the model wasn't too happy to be there either!
You can find information about Wallis paper here:
Wallis Paper @ Dick Blicks
I didn't realize it was developed by a Forum member, Kitty Wallis (if they are one and the same), so hopefully she'll see this and give you the personal scoop on the paper.
It is my favorite to work on, it has a lot of bite so I am not sure if people who use pastel pencil or Conte sticks would like it as much. The best way for me to describe it is, it is more like a pink fiberglass texture vs. sandpaper. The texture is not a round bumpy feel, but varies.
Hope that helps.
