Flatlock sewing A flatlock stitch is made by sewing the seam and pulling the fabric apart to flatten the seam. The flatlock stitch can be used both as a decorative construction stitch, sewing two pieces together (Standard flatlock stitch), or for embellishment on only one piece of fabric (Ornamental flatlock stitch). There are two ways to sew a flatlock stitch. Either with the wrong sides of the fabric together to create a decorative look, or with the right sides together, to create a ladder stitch. Standard flatlock stitch • Use the left or the right needle. • For 2-thread flatlock: Engage the 2-thread converter (see page 10). Thread the lower looper and the left (A) or right (B) needle. For 3-thread flatlock: Thread the lower and upper looper and the left (A) or right (B) needle. • Set the ATD to E for 2-thread flatlock and to F for 3-thread flatlock. • Place the wrong sides of the two pieces of fabric together to sew a decorative stitch on the right side of the garment. • Sew the seam, trimming the excess fabric. The needle thread will form a V on the underside of the fabric. The lower looper thread will pull into a straight line at the fabric edge. • Unfold the fabric and pull on opposite sides of the seam to pull the stitches flat. Standard flatlock stitch Ornamental flatlock stitch Ornamental flatlock stitch • Place the movable upper cutter in the B position (see page 9). The fabric should not be trimmed on this stitch. • Follow steps 1-3 above. • Fold the fabric piece, wrong sides together, to sew a decorative stitch from the right side of the garment (at the fold). • Position the fabric so the seam is sewn with part of the stitch extending off the fabric. • Unfold the fabric and pull on opposite sides of the stitch to flatten. Tip: The upper looper thread is the prominent thread in the flatlock stitch. Place a decorative thread in the upper looper and regular threads in the lower looper and needle. Ladder stitch To create a ladder stitch, sew with right sides of the fabric together. The needle thread will be the prominent thread that creates the ladder. 3-thread ladder stitch 22 Stitches & sewing techniques
