Usually canvas paintings are stretched on stretcher bars. I thought about other ways for hanging and developed other ways of hanging for my painting!
Painting on canvas "Blue Hour".
Not on stretcher bars, but with white wooden strips on the top and the bottom - it comes rolled, you just enroll it and it is ready to hang flat on the wall (see close ups).
A really unique and unusual way of hanging, reminding e.g. on old maps in school.
