In the first version I did my cutting as per the instructions in Ricky Tims' book where you have your 2 sections of fabric with 2 pieces of fabric sewing together, the seam line is at the bottom and the right sides of the fabric are together - see picture below. You then cut narrowest strips to widest strips from the middle to the outside of the 2 sections of fabric that are laid out on your cutting table.
I had a hunch that with cutting such long strips that it is likely that there is some inaccuracy in cutting and I wanted to try a different method. So here are my fabrics laid out ready to cut as per the book. These are the wrong sides of the fabric, with the seam line at the bottom.
