smiley face
With black thread and a tapestry needle, sew the smile between rows 2 and 3. First, make a small horizontal stitch in st 1 of the row, then sew running stitches around the circle to the opposite corner, mirroring the position to judge where to finish the point. Make another horizontal st at this end.
Sew the eye about 2 sts above the smile, then sew the smile back and fill the gap with running stitches.
Lastly, complete the smiley face by sewing on the eye.
