I feel really silly asking this question as after many looks all over the internet it doesnt seem to have been asked before. I have just got a new serger and it is all threaded up and ready to go….. so now what do i do? Where do I line the fabric up, my knife seems to be before the feeding teeth so the fabric wont go through and when I try to push it through all the threads get tangled. I found lots of tutorials on how to thread a serger but not what to do after, can someone please help?!?!?
