Introduction: I've always a lot of books, even as a kid. Arranging them is a consistent joy, but how I arranged them has changed over the years.
Alphabetical Order - Practicing what I learned in Elem. School. Exact date unknown.
Height - When the jagged tops of the previous arrangements started to bother me, & the smooth descending slope of book tops relieved the previous stress. Exact date unknown.
Color - Began as an art project my Junior year of college. 2012/2013. Current preference, because it is wildly beautiful (!!!!) & surrounding myself with beauty makes me feel hopeful.
