Paragraph 110. A seam may be made by overhanding together two selvage edges or two raw edges turned under. To avoid using a knot which would be difficult to conceal, you may fasten the thread by sewing over the end of it in the first few stitches. A knot may be used in overhanding seams which have the raw edges turned under.
This stitch is most commonly worked from right to left although some prefer to work from left to right. Hold the two edges together and overhand as explained in Paragraph 109.
The overhand seam is used in sewing any kind of seams where flat smooth work is desired as in the overhand patch (Par. 150) and seams of pillow cases.
