Dear Jan,
When sewing Twin Needle Pintucks, they don't seem to "tunnel" down the center as much as I would like. How can I correct this? -Anonymous

Dear Anonymous,
Try using Janome Silk thread in the needles and Janome Topstitch thread in the bobbin. Increase the needle thread tension to between 6 and 9. The weight of the topstitching thread will create the "tunneling" that you are looking for.
