>>Has anyone used it differently?
I met a mask maker who uses a similar paper in a negative plaster mold. The thin paper is used for the first layer so that it forms to the fine details of the mold. The thick paper is used after that, 2-3 layers, to strengthen the mask. She said that she did not think this paper would work as well for paper mache over a positive form. It is good for use in a negative mold because it is both flexible and strong.
