Knotted Stitch is a great stitch for clothing. While it is a slower moving stitch, it gives a great effect!
This stitch is done in two parts. The first is a steep vertical stitch over one canvas thread horizontally and up three vertically. It is tied with a Reverse Tent Stitch that bisects the stitch in half. 
It can be done all in one color, or you can use a second color for the "tying" stitch.
