Flatlock Sewing A A Flatlock (A) is made by adjusting the tension of the 3-thread overlock stitch, sewing the seam and pulling the fabrics apart to flatten the seam. The tensions must be ad- justed correctly for the fabric to pull flat properly. A Flatlock can be used both as a decorative construction stitch, sewing two pieces together (Standard Flatlock), or for decoration only on one piece of fabric (Decorative Flatlock). There are two ways to sew a Flatlock. Either with the B wrong sides of the fabric together to create a decorative look, or with the right sides together, to create a Ladder Stitch. Standard Flatlock, Wide (B) 1. Use the left needle. 2. Thread the lower and upper looper and the left needle. 3. Set the thread tension according to the stitch table on page 30. 4. Place the wrong sides of the two pieces of fabric together to sew a decorative stitch on the right side of the project. 5. 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. 6. Unfold the fabric and pull on opposite sides of the C seam to pull the stitches flat. Decorative Flatlock, Wide (C) 1. Place the upper cutter in the nonworking position. The fabric should not be trimmed on this stitch. 2. Follow steps 1-3 above. 3. Fold the fabric piece, wrong sides together, to sew a decorative stitch on the right side of the project. 4. Position the fabric so the seam is sewn with part of the stitch extending off the fabric. 5. 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 (D) D A ladder stitch is a flatlock stitch but sewn with the right sides of the fabric together. The needle thread will be the prominent thread that creates the ladder. SEWING - 35
