Patreon Oct 2014 is the subsection for sketchbook fillers from October 2014. It again consists mostly of images for the Patreon backers, and there are also three "milestone" images with topics chosen by Dan. This time, someone did take the two-panel before-after option.
On the final day, Dan posted four sketchbooks.
It starts with EGS Sketchbook Comic for 2014-10-02 and ends with EGS Sketchbook Comic for 2014-10-31, number 4 of 4.
