That's interesting. I just looked at some videos for the tube method and they do sew the seam on the straight and the resultant triangles have bias edges. I was shown this method at a quilt class, she called it the tube method, but we sewed the seams on a 45, just like the video of the tool does. I thought everyone did it that way!
