I seem to be doing something wrong but can't figure out what it is. My tension seems fine for regular sewing. When I try to use the hand-look stitches with Superior's Mono poly on the top and anywhere from 50-30 wt in the bobbin, I can't get the bobbin thread to pull to the top. I have adjusted my top tension up to 10 and am using the blue dot case after also trying the red but that isn't making much of a difference. I am going at the slowest speed. If I use stabilizer backed quilting cotton I get an almost okay result but nothing seems to work well. Of course I've cleaned my machine from top to toe, flossed, and turned it off and on a few times and tried several different needles as well.
I just tried to work it out on my M7050 which I bought for classes but it's "contour stitch" wouldn't do it either which makes me suspect I'm the problem.
I would appreciate any advice. Going to my dealer is out of the question due to travel restrictions at this time.
