9 – 3 Flatlock seams
Flatlock seams are ideal for many fabrics, including interlock, spandex, tricot, sweatshirt fleece, fake – fur and
synthetic suede. Flatlock seaming may be used on many woven fabrics, as well, but be sure to make a test
seam first to determine whether it will have the necessary strength. In any instance, the seam should be
considered "decorative" because the thread pattern will shown on the outside as well as the inside of the
garment.
Flatlock seams are sewn in the same manner as three – thread seams; however, after sewing, the two fabric
layers are pulled until the seam lays flat, and the two – threads form a pattern between them. Before sewing,
you must decide which stitch pattern you want to have on the outside of the garment.
If you wish to have the loop pattern showing, place fabric wrong sides together before sewing seam. (Figure
65).
If the ladder effect is desired on the outside, the fabric is placed right sides together. (Figure 66).
9 – 4 Flatlock tucks
Decorative tucks may be created on blouses, dresses, childrens and infants wear, etc., with the use of the
flatlock stitch. Either follow placement lines on your pattern or design your own tucks by stitching fabric prior
to laying out pattern pieces.
1. Set the machine for two – thread sewing with
stitch length and width as desired for finished
look.
2. Disengage the upper knife.
3. Fold fabric – right side out – along tuck
placement lines.
4. Position fabric under the presser foot with fold
aligned with the right edge of the needle plate,
and stitch the tuck to desired ending point.
