Paragraph 105. Tacking is a modification of the uneven basting stitch (Par. 104), except that the short stitches are usually made slanting or vertical. Tacking is used to fasten linings and inter-linings to dress or suiting material.
Tie a knot in the thread; insert the needle from the right side of the material; take a vertical or a slanting stitch about one-fourth inch long on the under side of the material. Set the needle forward in the desired direction one-half an inch or more. (See Figure 6.) Repeat until you have completely fastened the two pieces together. Fasten the thread by sewing over and over a short stitch at the end.
