Mix one part glue to 4 parts water to create a glue mixture.
Tear and add bathroom roll paper to the glue mix and massage it till it is quite smooth and becomes the consistency similar to soft clay.
The paper pulp should not be too dry or too wet. It will be sticky due to the glue mixture.
Get rid of any lumps or large pieces. Press and and knead it in.
Form a shape with the pulp. If it holds the form you made, it's ready!
Apply a thin layer on the entire surface of the sculpture. Remember to cover every corner and edge with paper pulp. The styrofoam should not be seen at all when you are done. You can use the paper pulp to change the shape of your styrofoam sculpture as well.
Use the paper pulp to make 3-D relief designs for your sculpture.
