I've had two and love them both. The secret to threading is PATIENCE, a small LED flashlight and the instruction book. After you have threaded it correctly, take the thread out and do it over again till you familiarize yourself with where each thread goes. One of my favorite tips is to match the thread color to the suggested thread color the shown on the machine, that way you learn what each needle does when it sews. Always start the threading with the lower looper, then upper looper, right needle and finally left needle. Hope this helps
