I've been working on one of my own quilts so it isn't perfect. I created a pattern to fit in the space beside each pieced fan and found that I needed to modify the pattern in many of the blocks so that it would stitch where I wanted it to stitch. This video shows how I used shape shift to alter the pattern slightly. It might not be clear in the film, but after touching the screen, I move the stylus to alter the pattern. You'll see I didn't need to move it a lot.
Shape shift is such a useful tool - try it out!
