I just bought the Huskylock 936 and now I need to know how to use it. I also bought the work book but that just shows how to set it up, what I need to know is under what conditions do you use which stitch for? So far all I have used is the 4 thread overlock. I want to make a simple, oversized kind of t-shirty thing. Do I use the 4 thread overlock or the 3 thread or which one? I haven’t worked out the cover stitch yet but I think that is for hemming. Is this right? Please, anyone with experience in all these different stitches could shed some light I would be truly grateful! Thanks!
