Grid Mixed Media Painting

I am obsessed with painting in a grid format.

This is the third sketchbook that I am filling up with grid mixed media paintings.  Some artists call then "grid journals" but I don't since I don't use words.  The reason I love this format is because it allows me to easily experiment with color palettes, mark-making, collage, and other ways to create little pieces of art.

Each square (which is my favorite format) is only 2 inches.  I don't think about each square but how all the squares interact with each other together.  This gives me freedom not to over-think everything and as my eye roams around the piece, I see where I need more contrast, more marks, and more shapes.  Every square turns out differently, even though I'm using the same paints and mark-making tools.

I think the reason I'm obsessed with this is that I can usually make 2 spreads a day and end up with something pleasing, but different than all the grids that I've done before.  It's kind of like working in a series but since these paintings are enclosed in a sketchbook, hard to display in an exhibit.  

​Maybe I should start making these grids on large pieces of paper so they can be mounted and hung on a wall.  What do you think?
