Thank you all for your quick responses! I should have given more info initially. I have experience with FMQ. I do know what eyelashes are and this is not my problem. It's just that I can see the top thread stitches on the bottom side. I have gotten it a little better by lowering the tension (as opposed to typically increasing it), and increasing stitch length (even though many say to set length at 0), but I can still see it on the bottom. This was information from a lady I received email from through Singer. I have gone through 4 trial "sandwiches" and have written all my settings down on the fabric beside each trial stitch. When you folks free motion quilt, what settings do you use? I do not want to mess with bobbin tension. That is set at the factory when it's built, and was told not to mess with it. Thank you!
