I have exhausted all attempts to get a good stitch on my new 770 QE Bernina. Spent hours at Bernina store with no resolution. Have tried tension, change bobbin case, tried all kinds of threads and needles. Even tried a solution to try an idea from Leah Day to not lower feed dogs and set stitch length to zero. Nothing has made a difference. It is called feathering and stitch looks it is one stitch with no division of beautiful stitches. Has anyone heard or seen this? It is disheartening! hope some one has an idea that will help solve the issue. Tension
is not the problem.
