Half-Back Stitch.—Half-back stitching is similar to the stitching. The long forward stitch on the under side is three times the length of the backstitch on the upper side, and a space the length of the backstitch is left between the stitches. See Stitching, [page 63].

Hemming.—A hem is a fold made by twice turning over the edge of a piece of cloth, and then sewing it down. The first fold is most important; if that is turned even there will be little trouble with the second. Trim the edge of the cloth before turning the hem. It is well to make and use a gauge of the required width. If a wide hem is turned, baste along the second fold or bottom of the hem first, and then at the top. On woolen goods or material that does not crease easily it is necessary to baste the first fold. Either bury the knot between the folds of the hem or leave one-half inch of thread and hem over it.

A. Hemming Stitch.

Hold the hem across the cushion of the left forefinger and point the needle a little to the left across the middle of the thumb. Take up a few threads of the cloth and a few threads of the fold and draw the needle through. Take care that the stitches are regular, of equal length and of equal distance apart. Do not confuse the hemming stitch with the blind stitch, or the damask hem. Join the threads by leaving a half-inch of the old thread and a half-inch of the new to be tucked under the edge of the hem and be hemmed over.

Teachers will find the following suggestions helpful in teaching the hemming stitch:

Put the needle in almost straight with the hem, not at right angles to it. Take up as little cloth on the needle as possible; bring the needle directly through the hem, making one stitch of it instead of dividing the stitch as in the blind stitch. Crowd the point of the needle under the edge of the hem. Do not insert the needle a distance from the hem, trusting to puckering it up.

B. Damask Hem.

Damask is a heavy fabric woven of heavy threads of one color in which the pattern is brought out by a change in the direction of the threads, and when new is stiff with much dressing. From the very nature of the cloth it is impossible to hem well with the flat hem. The two folds of the hem are turned the desired width and the hem is then turned back flat to the cloth and creased. The edge of the hem and the crease thus formed are overhanded together with fine even stitches. When laundered this irons perfectly smooth and the stitches do not show on the right side. Do not confuse this method of hemming with the flat hem, as each has its own use.

Overcasting.—Overcasting is done by taking loose stitches over the raw edge of cloth from right to left to keep it from raveling. The depth of the stitch depends upon the material to be overcast, usually an eighth of an inch is sufficient. The stitches should be twice as far apart as they are deep. The needle is inserted from the under side of the cloth and points a little to the left, making a slanting stitch. Keep the spaces even and the stitches of equal length. Always trim the edges before overcasting. Do not overcast a selvedge edge. Take only one stitch at a time and be careful not to draw the edge of the cloth.

Overhanding.—Overhanding is done by sewing closely over two edges of cloth from right to left. The cloth may have a folded or selvedge edge. Careful basting is necessary to good overhanding. The needle is placed at a right angle to the seam and should point to the chest. No knot is used; a short end of the thread is left and overhanded under. Hold the work horizontally along the edge of the cushion of the left forefinger and the thumb. Do not wind the cloth over the end of the finger. The stitches are straight on the under side and slanting on the top. Do not draw the threads tight enough to make a hard seam and also avoid a loose stitch that will not hold the edges together when the seam is opened. A deep stitch is not necessary for strength and will not look well on the right side when opened. To join the threads leave a half-inch of the old and a half-inch of the new, lay them along the edge and overhand over them.
