Some information, about how to remove serger stitching without cutting the stitching off, first take out the Right line of stitches that looks like a regular machine stitch then the left line which is a little harder to get a hold of, the the looper stitch will just fall loose.

Thank you for the info.

Find and remove your needle thread and the looper threads fall away. You can also gather by pulling up the needle thread. I didn't really like sergers until I purchased one with jet air threading. Such a game changer!

I find I can remove the stitches by running the un picker along the back side of the stitches while holding it flat.
