I wish I was closer to you and I could show you how. I use to sell and teach serger. The best way to learn is to thread each thread pathway with a different color of thread. It is easier to see the path of the thread with the different colors. There should be a thread chart on the machine some where, and there are usually color dots for the path of each thread. There is usually a door on the front of the machine that comes down. This is where the thread chart usually is. When you get the machine threaded and going, then the different color threads will help you to know how to adjust the tensions ( all those knobs on the front). A serger is a wonderful invention for sewing and finishing a sewn piece. I don't know how I ever sewed without one. It helps make your work look very professional. After you practice some and get the hang of it, then you can change the thread color. Be sure to use the needle thread the color of the project. Hope this helped some.
