My beautiful machine is sewing screwy. Awful loops on the bottom of my work. And building up in the bobbin area. I have cleaned it, changed bobbins and thread types, changed needles, different stabilizers, everything i can think of. Checked the settings on my sisters machine and made sure mine matched. Still looping bad on bottom. It was sewing fine and then started this in the middle of a design. Its not the design, stitched it fine on my sisters. Tried different designs on mine and still awful loops. What happened? Is it going to have to see the doc? Not sure I can go that long without it!!
