I truly enjoyed this class.  I have been doing Zentangle (tangling) for many years and I love finding new ways to use the method, so combining it with Mondrian's style was great!  A did a second copy of the first project using secondary colors instead of primary colors and included different tangles.  I did a second copy of the second project as well using lighter versions of the same colors in the background.  For all projects, I used Sakura Micron pens, Faber Castell matte graphite pencils, and Copic alcohol markers on 6" by 6" paper tiles.
