If you have a Bernina you can do the adjustment yourself. There is a balance on the machine. When you get the split picture up ...the one on the right is the one you adjust to look like what is stitching out. The machine will then adjust and this should take care of the problem. I made sandwiches and did a sew out of all. I had several that were off, but for some reason after I adjusted one they all corrected themselves. Crazy HUH!!!
