This row in DMC broder special is a combination of 2 of the same rows, but the second one is upside down. I stitched the buttonhole stitches in an angle.
I made the next row with light and dark blue perle 5. I switched colors in the first step of the stitch. I used 2 needles.
The last row is done in a variegated cotton thread. I alternated the direction of the stitch.
