I have the Babylock Espire and the 1/4" foot with flange is in constant battle with the feed dogs. I tried sewing jelly roll strips together and the seam was wonky all the way down. Had to rip it out. Now I use a regular piecing foot and if I need a guide, I just use a command strip on my machine. I also use a small clear acrylic ruler and measure the edge of the presser foot and adjust the needle to where it hits just to the right of the 1/4" mark on the ruler.
