I learned early on how to thread my serger from scratch every time. If I tried the "knot" method either the knot would come undone (because it wasn't strong enough) or it would be too thick to go through the places where it needed to go (because I made a big knot so it wouldn't come undone!). I understand that the newer sergers are easy to thread.
