I don't think it matters whether you paper piece this one or not. The nature of the design causes you waste some fabric. The only way that I can figure out how to make it without wasting fabric is to use hand-dyes or batiks for the strips so you can flip the fabric over to make the mirror image. I would also starch, starch, starch if I made it this way because all those edges are going to be on the bias. Most people probably would be better off marking the cut line, sewing the row together or sashing strip on and then cutting off the excess to control all that bias.
