A quicker method of catch-stitching is shown in Fig. 13. This stitch has not the strength of the first method and is only used in millinery and in dressmaking where the work is concealed. This style of catch-stitching is done from right to left.
A FLAT FELL SLAM has one edge hemmed down to protect the
other raw edge. It is used principally for underwear. Baste the
edges together, and sew with combination stitch. If the edges are
bias, sew from the broad part of the pieces to the narrow, to
prevent raveling and stretching.
Remove bastings, trim the edge toward you close
to the sewing line, and turn the other edge flatly over it,
pressing hard with the thumb
nail. Make a narrow turning,
baste and hem. (Fig. 14.)
A FRENCH SLAM is a
double seam encasing the raw seam edges. (Fig. 15.) Place the edges evenly together and sew close to them on the right side of the garment. Trim off all ravelings from the edges. Turn the wrong side toward you, crease exactly at the seam, and make a second sewing of sufficient depth to entirely cover the raw edges. This seam is generally used in making garments of wash materials.
