I went for fewer colors, tho' there are actually three different reds. I intended to make wonky triangles, but I also GOT some of the colors in the "wrong" placement by mistake. I'm leaving them.
Also the strips were not even width when I was done sewing the triangles together, so I cut two off them narrowing at one end, in opposite directions so the whole thing would approximate rectangular.
My current question is: better for the red triangles to point down or up?
