Machine problem sewing binding corners
I have a Brother Innovis 4000D that is a brat when it comes to sewing down binding at the corners. I use a double folded binding and when I come to the corner, with the mitred fold, the thread nests underneath, making a huge mess. I can hear it start to do it about 10 stitches before it hits the corner, so the foot is starting to lift. Any idea why it's happening and if there is something I can do to change this??? I have another Brother that this doesn't happen on but it frustrates me that I can't figure out why on this machine.
