I just used paper out of a drawing pad. You know how the paper in watercolor pad is textured and then the stuff in a sketch pad is really thin and flimsy? The paper from a drawing pad is smooth and heavier than sketch paper, so that's the stuff I went for. But definitely experiment with other types of paper, too! Can't wait to see it! I'm already following you so make sure to post it.
