4-thread overlock seam
A durable, flexible seam created by a serger that stretches with the knit fabric without snapping.
Where it is used
Sew Back Center Seam
p. 3- Place the back pieces right sides together, align at the center edge, and pin to match up the guide points. Insert the pins parallel to the center edge, about 3–4 cm apart. This way, the pins won’t get caught by the serger blade. Sew the seam on the overlocker set to a 4-thread stitch. Stop about 2 cm before the start of the slit, as shown. Thread the overlock chain into a knit needle or hook and tuck it neatly between the layers of fabric. With your sewing machine, finish the seam exactly at the marked starting point of the slit, as shown in the photo.

p. 4- Sew and serge the top's side seams at the same time using a 4-thread overlock machine, easing the front edge in the bust area. (Alternatively, sew with a regular machine, then finish the edges with a standard 3-thread overlocker.) Use a 0.7 cm seam allowance.

Step 17: Stitching armholes and straps
p. 8- Using a four-thread overlock machine, sew the upper pieces with the lining. Start at the seam joining the strap edges, then continue along the armhole edge, the top edge of the back, and finish at the side seam. Stop there.
