Once the paper is soft, now the mashing process start. Use a rubber handgloves to protect your hand and nail from print ink. Make sure this gloves is of your hand size.
Start with tranferring a ball of soaked paper to a second container. Add water in. Squeeze and tear the strip repeatly. Add water as necessary. Once done, pour to the third container. Repeat the process till you are happy with the condition of the paper.
What I do to make the mash more finer is by blending the paper with a DYI mixer by using drill. I tied curtain hook to a steel rod, insert to a drill and blend the paper for finer result.
In this process, adding water must be in caution as too much will just turn the mixture, too little just burden the drill. You can also use normal kitchen blender to do this too.
Now the paper is all set for the next step of the process.
