3. What are the different types of finishes I can do on a serger?
• Overlock stitch: An overlock stitch contains at least one needle thread and an upper and lower looper thread. The upper and lower looper threads are carried to the needle as the stitch is formed. It is almost like a back and forth movement with the loopers moving toward one another. The needle secures these looper threads at the point where the needle enters the fabric. The upper and lower looper threads lock or cross at the fabric edge (locking). The result is the upper looper thread on top with the lower looper thread on the bottom and the threads locking at the fabric edge and the needle.
• Chain Stitch: The chain stitch is a needle thread and a chain looper thread. The top of the stitch looks like a straight stitch and the underside looks like a flat loop. This stitch looks like what was used on sacks of flour, sugar or dog food. The same principal applies – find the right stitch and it pulls apart. Another common place for this stitch is woven pants such as jeans.
• Wave Stitch: The wave stitch, which is an exclusive Baby Lock serger stitch, is a decorative stitch comprised of a needle thread and upper and lower looper thread. A standard overlock thread is used in the needle and a decorative thread is used for the upper and lower loopers. By adjusting the threading path of the upper looper a wave is created in the stitch. When looking at the top of the stitch you can see that the lower looper stitch is pulled to the front while the upper looper thread is pulled to the fabric edge. This action creates a wave or hill in the stitch. The underside of the stitch looks like a standard serger stitch. There are variations on the wave stitch, flatlock wave, rolled wave and reverse wave.
