Hello ladies,
I have a friend that has the VIking Emerald, and she is wanting to know if you can do FMQ with this machine? SHe has already tried:n(1) dropping the feed dogs WHILE using her walking foot.
Her problems is this, her stitches are not consistent, some small & short, others long and loose.

Any suggestions on how she can do this?

Thanks ladies,
