How I Built A Mountain with  Toilet Paper                             And PVC Glue  There are many techniques to use to cover your mountains and hills, like using plaster of paradise or paper Mache using paper and home made glue. I did give much consideration into using one of these two techniques, but the technique I finally decided to use, was toilet paper and PVC glue. And I am really glad I have. Because now it is finished, it is as hard as a rock but light like fibre glass. It was kind of funny at the time choosing this technique been as in this time when I had decided to start doing this, toilet paper was very hard to get and you had to que up to buy just one packet. And no I wasn't one of those people that had an abundance of it left over and needed to figure out how to use it...
