Here is my Inktober Drawing for 2019. It was done on a 20×16 Bristol Board. I used the Zentangle method for the drawing. I marked the four corner, drew wavy lines and circles. I made sure there was 31 sections and use the 2019 Zentangle Inktober list to fill one section a day. On October 31, I shaded all section of the drawing. Below is the results.
I also did mini (3.5″ x 3.5″) drawings for Inktober. I used the list provided by Pattern-Collection website. Those drawings are on the Drawings page.
