With this bargello, you make 6 strip sets, then as you assemble the rows, you have to adjust some of them. So you look at the diagram and take off what you don't need on a strip, and attach it to the next strip. You continue to do this until you have your full row, which in this case is 39 squares. Because the pattern changes, so do your rows. On these first rows, even though my green strips have 7 squares I am only using 2 on each end in the first row, 3 in the 2nd row, and 4 in the 3rd row.
