6 X 8 Acrylic on Canvas Board (all three pieces)
I decided to work on a project today and yesterday that would consist of a grouping of all the same size canvas and each painting would be monochromatic. I chose green, blue, and purple because I wanted to stay in the cool range of colors. The above photo is similar to what the grouping might look like hanging on a wall. I just finished the blue piece today.
I arranged each painting side by side on the table, snapped a photo, then put white dividers in between them in GIMP (freeware photo editing software).
