I have never seen this quilt, but, here's my opinion.
Cut all dark strips 1 1/4" wide and cut all light strips 1 1/4" wide.
Sew a dark/light/dark set, sew a light/dark/light set, I would press these towards the dark. Then cut your strips in 1 1/4" increments.
Do you want the corners and center block to be dark, then sew a dark/light/dark to a light/dark/light, the sew another dark/light/dark below the light/dark/light strip. You should then have a nine patch block.
