You don't really need a pattern to do a simple bargello. Just sew all the strips together in a nice order of colors as you choose. Sew the top and bottom of this panel together making a circle. Then cut strips from that circle, changing widths of these cuts as you go. I started with 2.5, and went down to 3/4 inch. Then you can get wider and narrower as you choose. Lay out the circles and decide how to sew them all back together. Open up one seam of each circle so you have a flat panel in the pattern you want. Mine went straight up and down again. I call it "Magic Mountain". I changed my mind a few times, which means I had to sew the strip back into a circle again and open it somewhere else.
