NOTEBOOKS

Studies show that you remember stuff better if you write it down by hand as it engages the brain differently in all the good ways.  My notebooks are sized to hold any 3.5" x 5.5" notebook--I like the Field Notes books, but since I'm not always out in a field taking notes, I also like the generic books you can pick up cheap from Amazon.  I can build these from most of my current leathers.  Priced from $95.
