A means of fastening together two or more pieces of material.
Single and double seams. For the former the following stitches are used, the running; stitching; backstitching and varieties of these; overhanding, and fine-drawing. For the latter, felling, French-seam, overhand and fell and counter-hemming. Double sewing is used in seams where greater strength or beauty is required than the single stitch can give. In dressmaking and tailoring there are many special names used such as lapped, welt, strapped and slot seams; these are, however, but varieties of those mentioned above.
For the first practice it is sometimes better to use material on the straight of the goods and colored thread, as the work is easier on the straight and the imperfections will show clearly. Seams in such garments as chemises, petticoats, nightgowns and drawers are, however, usually on the bias or a straight piece is united to a bias. It is well for inexperienced pupils to practice on a piece of cloth before applying on a garment, but the moment they can do fair work they should begin on a real garment, small or full size. (See Application of Stitches No. 23.) In many schools the first practice is given on coarse, unbleached muslin, but it is so much more difficult to work on than on a good quality of white muslin that it is unnecessarily discouraging to the pupils.
Garments in which various single and double seams are used should be brought to the class and their form and adaptability discussed. The teacher can use her judgment in discussing or practicing the various forms of seams used in dressmaking and tailoring.
