when i started these little paintings, for some reason, i put the striped border along the top and bottom or two sides. i am not really sure why i did this initially. maybe the painting needed something....but i did continue to do it and i like it. it unifies the series. although the edges always have it, sometimes i don't add it to the front if there is not space or i think it will deter from the composition. sometimes it gives me a chance to add a color if i feel the painting needs a little something.
in case you were wondering!
