Paragraph 121. Single featherstitching consists of a series of even slanting (or bias) stitches so taken alternately on right and left sides of a central line as to form an ornamental row or border.
NOTE: Your first effort at featherstitching should be on the edge of a hem, a seam, or a well marked thread in the material which will serve as a central line for your stitches. After some practice you will be able to follow an imaginary line.
To make this stitch, first conceal the knot by bringing the needle through from the under side of the material slightly to one side of the central line. With the thumb of the left hand, hold the thread down in front of the needle and take a slanting stitch on the opposite side of the line. Make the needle point toward the central line (See Figure 20) slanting at the true bias (45°). Hold the thread down in front of the needle as before and on the other side of the central line, and slightly ahead take a similar slanting stitch. Continue the above process using great care to make all stitches the same size and slant. This featherstitch is used considerably for decorative purposes on infants' garments, wraps and blankets. It is also employed in a great many ways in artistic needlework.
