Thank you! This was not really as challenging as it may look. I used a 9 degree, circle wedge ruler. (long, will make 36" circle) First sewed together two alternating fabrics to make a 24 inch row of 2 1/2 x 6 inch strips ( like a keyboard row using only two alternating fabrics). Then I added a row under that of one solid fabric 2 1/2 inches, then another solid row (you can make the solid rows as deep as you like as long as when finished your total piece is at least 14 inches x 18 inches wide to be able to cut a 12 1/2 x 12 1/3 inch block. Then cut "v" shaped strips by alternating the ruler from point upward to point downward.(Instructions come with the ruler. Then sew the strips together in the same order they were cut. Just straight stitch sewing and careful cutting. This ruler is great for making a lot of fun things.
After sleeping and dreaming about this block, I made a minor adjustment. OCD???? A little
