why i tell my sister to make paper ...

Because making paper is her truth, an anchor, a centering calm in whatever craziness she happens to be navigating.  It's what she's been about for as long as I can remember.  It's just what she does, not as an assignment, or because someone expects it, or because she's making a living at it.  She does it simply because it's who she is and what she's about and because it brings her joy -- an existential touchstone and talisman. The fact that she also does make a living at it is a blessing, but not the reason it's core.
