1.These first few rows are variations of this stitch, the variations are in height, width and angles.
2.two or more rows of this stitch are worked in various ways in these samples.
3.The stitch is worked in a curve in the first row. Both sides are worked in the second row. The triangles are worked alternatively in two heights in the third row. The buttonhole stitches are worked at an angle in the fourth row. I like this row.
