Anne, it's not that hard. If you want bars that are 2 inches by 8 inches, make the first bar with an 8 1/2 inch strip with a 2 1/2 inch square. Stitch and flip. Next bar is a 61/2 inch strip with a 4 1/2 inch strip. Stitch and flip. Next one is 4 1/2 inch with 6 1/2 inch and so on. Basically, imagine a bar with a HST inserted. The HST steps down a step in each bar.
