Correctly finished stitches
1. Upper looper thread (blue).
2. Lower looper thread (red).
3. Right-hand needle thread (green).
4. Left-hand needle thread (beige).
Perfect stitch formation is when both looper threads meet
at the fabric edge. The needle threads form straight stitch-
es for a stretchy and durable seam.
