You can use the same color or two different colors of thread for decorative stitches. Twin-needle sewing works well with these stitches: the Straight Stitch (6-10)-and the Zigzag Stitch (2). Be sure that the two upper threads used for threading the twin needle have the same weight. If the threads do not have the same weight, the stitching may not be consistent.
