Being that I have only used a serger once (yes once and in high school no less) and I cannot figure out how to thread the thing or it needs to be fixed because it will not make a chain or sew properly, I have taken it in for servicing. It will come back threaded (thankfully, because that was a pain!) and should be in working order.
I am super excited about getting it back so that I can use it and make all sorts of things!!
