Sandy S...thanks for all the tips...I have done most of them already. It's doing better, but still have some tiny peeks of bobbin showing around my curves and loops. I've turned my top tension just a little bit to keep seeing if I can correct it....just doesn't seem to have spot that will correct it. My bottom tension looks great. I'm hoping that when I quilt my "real" quilt (Not my sandwich practice) that those little peeks will disappear into the quilt.
