Pattern Story

When our son brought home his interest in irrational numbers and mathematical theorems, his excitement was contagious. His knowledge far outstrips mine, but I shared his fascination and was inspired to plot the numbers of e using a color algorithm— my own take on a color trajectory.
I wanted to engage numbers in a new way and found there was an architecture, a different kind of reveal as I painted row after row of squares that looked like chiclets. I found cadence in irrationality and a new correspondence with color.

Product Story

When I was nine a family friend gave me The Nothing Book. I carried it everywhere and this habit became permanent — I am never without my journal. My sketchbooks hold my brain: the galumphing to-do list, jottings, inspiration, places to visit, music to listen to, books to read, movies to see, endless doodles, potential painting titles, dreams and schemes, kids appointments, my calendar, and the rest of the beat. Colorful list notepad.


Mohawk double-thick cover printed on 100% post-consumer waste stock. Mohawk 100% recycled 70# white paper, printed on front side with ruled lines and boxes to check off completion of your tasks. Recycled euro book board back cover with foil stamp logo.
