Rya Stitch?

I’m trying to add some fringe on a canvas and was going to do turkey work but all of videos show the stitch working in a horizontal line. The hem area where I’m trying to add fringe is at an angle. A woman I met today recommended the rya stitch and said it’s basically turkey work but you can hop around rather than working in a straight line. Can anyone explain how this stitch is done? I can only find tutorials for embroidery and rug making. Thanks!
