Could You Go Without Toilet Paper?

I came across this story someone posted on Facebook about a growing trend of people who chose to stop using toilet paper.  Yes, for some toilet paper is something most of us can't do without, but there is a growing trend of folks who are choosing 'greener' alternatives.  I guess there are some chemicals that are used in the paper and to also save trees are the reason that these folks to make the switch.  What many are doing is using a reusable cloth toilet paper, some say they use flannel cloths which them kept in a box by the toilet and would put in the washing machine every couple of days. They are also saving a substantial amount of money as well, some as much as $20 per month!
