Kelly, I hope I can be of some help to you. I didn't watch the entire video, but I have done "tube" quilts before. Not sure if there were 2 or 3 strips on each side -- really doesn't matter. Those will be pressed toward the darker fabric (the print in the video). THEN you sew the two different strip sets together on both the top and the bottom. This is what you will press flat, even though it is connected on both sides (the "tube). Now the cutting -- I take the ruler clear to the top of the fabric, though I'm thinking MSQ co told you to take it to the seam. It's not a big deal to rip out a couple of stitches. Since you are turning your ruler, your resulting squares will be different. DO be careful handling them as the edges are on the bias. Hope at least some of this helps. Linda in Missouri
