Fill to full a basin/baldi with shredded newspaper.
Fill with water and add a little bleach to disinfect the paper.
Step in on the paper to make it compact and compress. Do this a couple of time to make the paper soaked. Add more paper to fill the space. Step in the paper again. Cover and set aside for a day to soften the paper. Note that not to keep this for too long as the soak paper tent to smell with time.
