My elderly Bernina 930 (mechical) sews a perfect stitch from the start. Much newer Janome 6600, computerized, makes a thread mess every start so I start with a tag (fabric). I am wondering about those who are sewing quilt pieces together for their leaders, don't you get a thread mess at the beginning of those? On my Janome I would need a tag for the leader...........don't quit get how this works.
