Pieced with Art Gallery fabric, Warm and White batting and Art Gallery fabric backing. I made a new bobbin (using the Pfaff bobbin) with my King Tut 40 wt thread, inserted a new 90/14 needle and took off--only to have skipped stitches immediately within the first 3 inches of sewing! I've completely rethreaded the machine multiple times and changed the needle thinking maybe I had an imperfect one out of the package, lowered the foot pressure--all with the same results. It sews beautifully on two pieces of fabric with no batting. So it either doesn't like my quilt sandwich or this operator has alot of error! Any and all thoughts appreciated!!
