I'm using green in my top looper and textured thread on my bottom as I'm sewing spandex.
I think the problem is my left needle thread (which you can see is totally loose on the back) as I can remove that needle and thread entirely and sew a balanced 3 thread overlock after some tension adjustments. I've rethreaded, changed needles, and tried different combinations of tensions. I've only used this machine on a few projects since I got it 6 months ago, so the machine is still in like new condition. Any ideas?
Thanks in advance!
