Papercreters: [papercreters] Re: Papercrete roof panels?

Yes, I have used the coated burlap (or in my case, I used old bed
blankets and old clothing ) to make large stones for landscaping the my
yard, I first draped coated blankets over an old tub and some buckets to
give it a shape, after dry I poured the interior of the stone with my
formula of PC, it has been laying out in the yard almost a year now and
I don't see any damage.
