You start off by sewing strips together; then when you get enough strips together you sew the first strip to the last strip and you have a tube. Like strip #1 to strip #15. This is the way I was taught to make mine and it is so much easier than sewing all of those little pieces together. You need to make sure as you cut you tube into section that after about every 2 to 3 cuts you square it up again to that it stays straight. I hope this helps.
