(4) Top or over-sewing stitch (fig. [11]).—This stitch is used for joining selvedges together. To keep the two pieces even, it is better, either to tack or pin them together first. Insert the needle, from right to left, under the first thread of the selvedge, and through both edges, and sew from right to left, setting your stitches not more than three threads apart. The thread must not be drawn too tightly, so that when the seam is finished and flattened with the thimble, the selvedges may lie, side by side.

Another kind of sewing-stitch (fig. [12])—For dress-seams and patching; sew left to right, tacking or pinning the edges together first, and holding them tightly with the thumb and finger, to keep perfectly even.
