I write almost exclusively with fountain pens these days. The only real exception is my daily schedule (the Full Focus Planner), in which I use a Blackwing 602 pencil because appointments have a habit of changing.
I am trying to write letters on a regular basis, and I am in a long term project of handwriting a copy of the Bible.
I love Rhodia notepads for general use, Triomphe (Clairfontaine) paper for correspondence, and any notebooks that have Tamoe River Paper. For my Bible project, I’m writing with archival quality ink (Noodler’s & De Atramentis) on loose leaf Tamoe River paper, which I intend to have bound at the end.
