The corners on my a quilt are developing a strange shape. I hope you can tell by the photo that they are "jutting" out to one side. It seems like there is too much fabric in the corner so it bunches up a bit. I machine sew to the front and then ladder stitch to the back. I have used this technique on several other quilts and don't remember having this problem. In addition, the stitching on the front is pulling out at the corners. What is going on? Any advice out there?
