French Seam
A French seam is sewed twice—first on the right side as near the raw edge as possible. Cut off all frayed edges, turn the material by folding on the seam or line of sewing, so the seam is folded inside and the second sewing is on the wrong side below the raw edges. This is not a good seam for underwear worn next the body, as it leaves a ridge on the wrong side, but it is useful for skirts of thin material, etc. It is more easily made than a fell.
Beaded Seam
Beaded seams used for fine white work have a line of beading overhanded between gores, hems, or gathers. The hem along the seam should be folded on the right side, leaving a perfectly flat surface to iron on the wrong side, and finished with an ornamental stitch covering the hem.
Slot Seams
The slot seam, used in cloth dresses and jackets, requires exact basting with silk or very fine thread with small, even stitches. If a coarse thread is used, the material will be badly marked. After basting, press the seam open as if it had been stitched, and baste the strap or under strip of the dress material (which has been cut perfectly straight and even) over the wrong side of the seam, having the center of the seam on the center of the strap. Stitch any width desired beyond the center through the three thicknesses. This will hold the seam in position. Now remove the bastings from the seam and the slot effect is complete. If desired, there may be a double row of stitching, an extra row on the edge of the fold or plait. These seams may be finished at the bottom with arrow heads or stitched designs. The lines of machine stitching should not end without some ornament to appear to hold the plait.
