I have a Sweet 16 sit down and am hoping to quilt a quilt with Superior Monopoly on top and red Bottom Line in the bobbin. I have the tension to I am not getting red picks on top but am not happy with the bottom stitches - they are not the clearly defined stitches I am used to. Should I be able to use this combination? Do I need to use Monopoly in both upper thread & bobbin? If so, is there something I need to do to the bobbin winder to wind the Monopoly on a bobbin? Thanks for any help.
