When going to toilet in the woods in the summer time you can always use leaves or moss. But in winter time the leaves has fallen off and the moss is buried under snow.
This weeking I walked on a trail near my parents home. The 2nd day I had to go, but I had forgot to bring toiletpaper. But I remember reading about making snowballs to use as toiletpaper in a book by Lars Fält. Better to use snowballs then not wiping my ass at all I thought. So after making a couple of snowballs I did what i had to do and after I sued the snowballs to wipe my ass. Surprisingly it worked great!!!
The snowballs works best when are shaped as a drop.
