Here is a link to a picture of Swiss granite paper shown at Wikipedia:
http://en.wikipedia.org/wiki/File:S...per_SC65.jpgUse a good light and a good magnifier, and look for the telltale "squiggles"
in the paper (not
on the paper). As tongman says, they are not always obvious, and they may not be as clear as they are on that Wikipedia picture.
Good luck.
