I want to add my recent experience in case some else runs into this same issue. I have a Baby Lock Journey and was having a problem with the walking foot skipping stitches. I tried all the usual fixes - new needle, check bobbin, cleaning lint out, etc - with no improvement. I had just had the machine serviced a few months ago but I ended up taking it back in because of the skipping. The technician called and said the problem was with the walking foot, not the machine and he made an adjustment to the walking foot to solve the problem. This really surprised me. I didn't know the walking foot could be the the reason for the skipped stitches and I'm so glad it's fixed.
