Avante user. Sewing on batik top, warm & natural batting, cotton backing. Just took a cotton on cotton quilt off that sewed dreamily. This one won't keep stitches. Makes 4 or 5 then just punching holes. Bobbin thread still following along just not coming up. Same type thread as before. Tried new needle, new size needle, new bobbin, rethreading machine, changing tension, quilt does not appear to be too taunt, what else can I do?
