Two rows are even prettier.
To work the stitch, bring the needle up through the fabric at 1, shown next to the black dot, and follow the numbers in the stitch diagram. Each stitch is over three threads and you always go down into the centre of the eyelet. Work each leg of the eyelet twice.
Pull the thread moderately when you bring your needle up through your work. Take care however when you come up after that long stitch, at 9 and 17. It's rather easy to pull that long stitch too tightly.
